Fostex VF16 16-Track Digital Multitracker
by Derek Johnson and Debbie Poyser

Everything comes to he (or she) who waits, as the proverb says, and in the case of 16-track digital multitrackers it's certainly true. Those musicians who kept their nerve during the initial rush of portable hard disk eight-track machines, confident that greater numbers of tracks for not too much more money must surely follow, have now reaped the benefits of their patience. A slow start saw the market dominated by early birds Akai, with their 12-track DPS12, and Roland, with their very full-featured but occasionally complicated 16-track VS1680. Then Korg successfully stretched their appealing D8 concept to 16-track status. Now two further digital 16-track mixer/recorder combos, from Fostex and Akai (the DPS16 was reviewed last month), are poised to hit the hi-tech music stores, and coming soon is a promising Yamaha contender. As the old bus adage has it, there's none for ages, then loads come along at once...

One might have expected Fostex to have entered the stakes earlier with their VF16 portable 16-track, which is the subject of the review in hand. After all, the company has a five-year history in digital recording, a healthy back catalogue of eight- and 16-track professional and project-studio machines, and a record of early popularisation of new technologies. A closer look at recent Fostex history, however, might fuel some speculation about why there's been a slight delay. Though they've made digital recorders aplenty, it's only around 10 months since the release of the first ever Fostex digital mixer, the moving-fader-equipped VM200. If Fostex wanted their portable 16-track to have the advantages of a digital mixing section (as opposed to the analogue mixers of their previous four- and eight-tracks), it made good sense to wait until the necessary technology was in place.

But though Fostex haven't managed to be first with a portable hard disk 16-track, they have managed to be cheapest — so far. The VF16, which features 16-track simultaneous recording, 'virtual' tracks, editing functions, the aforementioned digital mixer with automation and 16 physical faders (plus master fader), built-in effects, and onboard dynamics, comes in at just £1099. Aside from cost, another advantage of the new machine for anyone who's used previous Fostex digital recorders is familiarity. They've stuck with their usual reliable operating system, which runs through the whole Fostex family from top to bottom and offers a tape-like feel with largely straightforward operation.

NEW LOOK

Digital mixing isn't Fostex's only departure for the VF16. It's also their first product in ages not to be finished in Fostex 'greige', that smart but nondescript shade that matches many a computer. Instead, the VF16 has a rather more appealing charcoal paint job with pale-grey accents. It's reassuringly chunky in build, with a solid, compact wedge shape, and is pleasantly heavy to pick up.

The left two-thirds of the front panel are devoted to mixing duties, hosting two rows of 60mm faders (with illuminating channel-select/mute buttons) and three sets of buttons dealing with automation, effect editing, and setting up of channel parameters such as pan, EQ, and aux sends. Obviously, with a machine of this size quite a bit of the setting up is done in software, via the display, but at least Fostex have provided a hardware fader for every channel. However, even before we started to use the VF16 we were sorry to see that there were no hardware pan controls, and this feeling didn't go away when we did start to use it. Panning is such a basic part of mixing that one really does miss a hands-on control One idea for a VF16 update might be a software switch to turn the faders into pan sliders that just happen to have been rotated by 90 degrees (no extra hardware required).

The rightmost section of front panel is the recorder, looking very much like a stretched VR800 (Fostex's recent stand-alone digital eight-track recorder). The rather small backlit display, made to look larger than it is by an imposing raised surround, is accompanied by a group of round buttons concerned with audio recording and editing functions, plus a transport section and Jog/Shuttle wheel. Four utility buttons round off the recorder section.

The VF16's eight analogue inputs (1-6 on unbalanced jacks only, 7 and 8 with additional XLR connectors) are situated towards the rear of the front panel, which is good for accessibility. As you'd hope, the two XLRs have phantom power (switchable, but only as a pair), for the quality condenser mics so many project studios use these days, and insert points for favourite external processors. Each input also has a trim pot, plus a peak LED that flashes 2dB before clipping occurs.

A nice feature of the VF16 is that its eight digital inputs, in the shape of an ADAT-format optical connector (this and its accompanying ADAT output double as stereo S/PDIF I/O), can be recorded at the same time as the analogue inputs. You don't even have to put your thinking cap on to see that all 16 tracks could thus be recorded simultaneously, potentially good for live recording of even a large band. Add Fostex's £199 VC8 two-way ADAT-to-analogue converter box and all 16 tracks of simultaneous recording could be analogue, with help from the interface's eight phono inputs. Accompanying the digital I/O on the VF16's back panel are a small SCSI socket for connection of backup hard drives and CD burners (but not for direct recording); a footswitch socket for foot-operated punch in/out; MIDI I/O; an analogue master stereo output (on phonos, sadly); the two aux sends, sharing one stereo jack; and the mains power socket.

THE KIT INSIDE

The VF16 comes with its supplied 5.1Gb internal EIDE hard disk ready-formatted and capable of storing more than 15 track hours, dynamically allocated, with 16-bit resolution at a sample rate of 44.1kHz. The fitted drive, by the way, can be easily replaced with a more capacious one if desired. Alongside the 16 'real' tracks assigned to mixer channels, up to eight additional 'virtual' tracks are available, offering limited flexibility for alternative takes, and also some spare capacity for track management during bouncing.

Fostex's OS is actually beginning to look a little elderly with respect to virtual tracks. It would appear that their software allows for a maximum of 24 tracks, whether those are real or virtual. In the case of the company's recent 8-tracks that figure breaks down to eight real and 16 virtual, but is carved up into 16 real and eight virtual with the VF16. Ironically, when you have 16 real tracks at your disposal, opening up the possibility of more complex arrangements, it's arguable that you need more virtual tracks, not fewer. Surely Fostex will attend to this shortcoming soon. In the meantime, eight virtual tracks will have to suffice — it's no bad thing to have to make certain decisions early, anyway.

RECORDING ANGLES

Recording audio with the VF16 can be undertaken via either the 'Direct' or the 'Buss' method. The former uses a simple, fixed input-to-track relationship, whereby the inputs, labelled A-H, are routed directly to tracks 1-8 and/or 9-16. So when you choose Direct recording, audio from analogue input A will always be routed to track 1 or 9, or both, if desired — though no practical application of the last option comes to mind! Incidentally, if you have ADAT-equipped instruments, or an ADAT-to-analogue converter unit, and want to record to all the VF16's tracks at once, Direct record mode is the one you'll need. For those who have an S/PDIF-rather than an ADAT-equipped sound source, up to 10 tracks of simultaneous recording will be possible: two from digital inputs through the ADAT connector (doubling as an S/PDIF port), and eight from the analogue inputs. The only thing to bear in mind is that there are no digital processing facilities available to the input channels, so you won't be able to record with EQ, for example.

The second recording method, called 'Buss' mode, is rather more flexible and allows audio appearing at one or more of the analogue inputs to be routed to one or two tracks of your choice. You might use this method, for example, to record a drum kit miked up with four mics to a stereo pair of tracks, but the technique can also be used for bouncing multiple existing audio tracks into mono or stereo. In the case of Buss recording, the mixer section effectively acts as a submixer — all audio, whether external or on disk, has access to pan, EQ, onboard effects and, to a certain extent, dynamics. As with the VM200 digital mixer, subgrouping as such isn't provided, but Buss record provides just enough of the same facilities for most uses. Buss mode also allows you to simply route one analogue input to one track of your choice, rather than being restricted to the preset routing of Direct mode. It would be useful especially when a mic is the sound source, as the two XLR mic connectors are on inputs G and H, which are automatically routed to tracks 7/15 or 8/16 in Direct mode. If you need the mic inputs to go to other tracks, Buss mode is a must.

Once you've decided how you'd like to record, the process is as easy as with Fostex's other hard disk machines. First, decide the tempo and whether you'd like a metronome, then set up a tempo track within the VF16 if your song includes tempo changes. A nice feature is that audio is captured during the count-in period (if you've set one), so there's no need to ever lose an up beat. Next, set the right level for the incoming audio with the relevant trim pot — the display, small as it is, fortunately provides clear and accurate feedback of the pre-fade level going to a track. There's an Auto Repeat function that lets you set up a loop to rehearse with, if you like, and then it's simply a matter of committing the performance to disk.

If what's been recorded is not quite up to scratch there's one level of Undo, and if just one or two bits need redoing there are three ways of accomplishing punch-ins: manually (via a front-panel button), with a footswitch, or by pre-programming the drop-in using the dedicated Auto Punch In and Out buttons. It's easy to do and results are very good indeed.

Generally navigating through tracks is straightforward. The fast-wind buttons behave like those on an analogue machine, but with the option to instantly return to zero, and for more exact location the Jog/Shuttle dial can be used to move quickly through a track and then zoom in precisely, scrubbing through the audio one sample at a time if you wish. Up to 99 locate points per Song can be set too.

CLOSE TO THE EDIT

The audio editing capabilities of the VF16 won't compete with the typical sampler or computer recording system, and editing is not 'playlist' style (where no new audio is created by copying operations, the original audio segments simply being rapidly referenced and played back at the desired points). However, for basic assembly editing the VF16 offers enough flexibility. Cutting, pasting, moving and erasing operations, across single or multiple tracks, are pretty much identical to those on previous Fostex digital recorders: simply highlight a region of audio using the Memory keys, and select the edit function required. One thing we've moaned about virtually every time we've reviewed a Fostex hard disk multitrack is that audio pasted to a new location overwrites the audio already at that point. No option exists for shoving the existing tracks along to make way for the new section. Fostex haven't yet attended to this small irritation, and you still have to get around it by using 'Move' to make space into which audio can be pasted.

One enhancement over older machines comes, paradoxically, courtesy of the display which, incredibly, actually appears smaller than on Fostex's earlier FD8 eight-track — and even that wasn't terribly generous. At a time when Fostex really could make their displays bigger, to compete with the likes of Korg's D16 touchscreen and Akai's sexy DPS16 flip-up LCD, this could be seen as rather odd. However, on the plus side, the VF16's display definitely is brighter, higher resolution, and more suited to graphics than earlier Fostex LCDs. It now supports a full waveform display, rather than simply using bargraph meters to represent a waveform, as with previous machines. Fine-tuning start and end points while manipulating audio is consequently much easier.

It's also good to know that, because the VF16 can export tracks one at a time in the popular WAV file format, via the SCSI interface, VF16 audio could be edited with a computer editing package. Since WAVs can also be imported, edited tracks could subsequently be returned to the machine for mixing.

FIX IT IN THE MIXER

The VF16's mixing section has a decent set of features (though we were unable to find a way of soloing channels) and can be thought of as a straightforward 16:2 stereo mixer. The three-band EQ, offering identical swept mid and high bands and a shelving low band, is available to every channel and the master output, and is set up via a neat, grid-like graphic display showing an EQ curve which changes in real time as parameters are altered. Speaking of neat graphic displays, Fostex do their best to make panning as painless as possible via the LCD, given that there are no real pan pots: hit the Pan button and a screenful of 16 graphic knobs appears. Pressing a hardware channel-select button for the channel in question causes the corresponding on-screen knob to flash, and then its setting can be altered with the Jog/Shuttle wheel, which doubles as a parameter dial. Still not as good as real pan-pots though. The aux send display, which you need for setting up the two sends to external processors and the two to the internal effects, works in a similar way. Sends, by the way, are individually switchable pre-/post-fade.

Additional helpful screens include Channel View, which graphically presents level, pan and aux sends for an individual channel of your choice, and Fader View. The latter gets around the problem of drastic mismatches between the front-panel positions of the physical faders and their functional levels within the operating software, especially when automation is being used. There are also some useful options to help you relocate the physical faders to their correct values as shown in the display, something which could be necessary at various times during automated mixing.

It's good to see that Fostex have included dynamics processing, which was a notable omission from the VM200 digital mixer, on the VF16. The facility runs to a conventionally specified, workmanlike stereo compressor fixed to the master output and a further dual compressor which can be applied to channels 13/14 or 15/16 (you can choose to use just one half of the compressor). The latter can't be deployed anywhere else on the VF16, though it's possible to get any track compressed by indulging in a little track exchanging. Unfortunately, when a compressor is selected, the EQ for both the channels in the selected pair (even if you only want to compress one channel) is disabled. This is processor-power juggling reminiscent of the compromises found on the VM200 (though, happily, engaging the master compressor has no effect on master EQ availability). Fostex redeem themselves slightly by making it possible to compress incoming audio with the dual compressor, using Buss record mode. If you need more than the onboard compressors offer, don't forget that you can make use of an external compressor (or any other signal processor) via those insert points on analogue inputs G and H.

The VF16's dual effects processors are based around the same ASP (Advanced Signal Processing) technology used in the VM200 mixer. They offer more in the way of algorithms than the VM200's processors, but they don't have the VM's preset library or user memories. One processor is devoted to reverbs and delay/reverb combinations (28 effects in total, including rooms, halls, auditoriums, stadiums, garages and plates), while the other offers the same 28 effects plus 10 extras (delays and timed delays, a chorus, a flange, and two pitch-shifters). The chorus, flange and delays are usable enough, and it's good to see a dedicated tempo delay, but the reverbs tend to be ringy and metallic rather than natural-sounding, and are best used sparingly and carefully. The effects are not extravagantly editable, either, having just five parameters each (Level, Reverb Time, Pre-delay, HF Ratio and Early Reflection Level in the case of the reverbs). The lack of memories means that any user effects setups have to be saved in mixer Scene memories (see 'Automatic For The People' box for more on the VF's Scene automation).

Overall, we felt that the reverbs weren't really up to being used on anything other than demos, but fortunately the external aux sends mean that you're not locked into the onboard effects, though the lack of dedicated aux returns opens an interesting can of worms. Normally, in the absence of aux returns, one would expect the analogue inputs to be deployed for returning effects. Korg's D16 and Akai's new DPS16 both let the user do this and offer extra mixer horsepower in order not to compromise the playback of disk tracks. Not the VF16, unfortunately: the analogue inputs can be used during a final mix, for effects and/or inputs from synths, samplers etc that are being sequenced, but only at the expense of the audio that might be occupying the corresponding hard disk track. In short, the mixer channels with analogue inputs can either play back the audio tracks you've recorded or be used to bring effects or sequenced instruments into a mix — not both.

In trying to find a way around this, the best we could come up with was bouncing together some of the 16 audio tracks to free up inputs. To accommodate an external stereo submixer, for example, you'd simply need to free up two audio tracks. The submixer could then handle any sequenced sound sources or external effects returns. The sans-submixer alternative is bouncing your funky 16-track mix down to eight tracks just so you can route the stereo outputs from a couple of synths and a couple of effects processors through the multitracker's analogue inputs! If there's any way Fostex can redeploy DSP in a software update, they should.

VERDICT

On the whole, this is a good machine. It's easy to use, very stable (never crashes, just like every other recent Fostex hard disk recorder we've encountered, and so unlike every recent computer system we've had!), and is capable of producing great results. We would love to be wholeheartedly positive about it, but there are those downers — a limited number of virtual tracks, the small display (though it is perfectly usable), slightly inflexible compressors, underwhelming reverbs, a few automation niggles, and (most annoyingly) the fact that the analogue inputs can't be used freely on mixdown. The VF16 also doesn't offer anything other than 16-bit, 44.1kHz recording, while some of the competition is now providing up to 24-bit, 96kHz (though, to be fair, few people actually need these facilities yet).

There's strong competition out there for the VF16, and you should consider carefully which machine best fits your requirements for the money you have to spend. Nevertheless, it's a measure of how usable this one is that its flaws don't, in our opinion, turn it into a lemon, as long as you go into any purchase fully aware of them. We enjoyed using the VF16, felt it was fast in operation, and got some fine-sounding material from it. Fostex are still offering the open-endedness of an ADAT interface, have been sensible enough to fit phantom power and insert points, have allowed you to export and import material as WAVs, have provided a fader for every channel, and are only asking you to part with £1099 for simple-to-operate 16-track digital. It's got to be worth a look.

Fostex VF-16 Digital Multitrack Recorder
by Nick Baily

Self-contained ministudios are always about compromise. Features, I/O and components are all shaved and rearranged with an eye on the all-important price. Get it right and you’ve got a product that’s versatile, affordable and useful. Skimp too much on important areas and you end up with something that "slices and dices" but can ultimately be frustrating.

That said, compromise is becoming less necessary for those in the market for a compact, inexpensive recording and mixing device. As someone who spent hours messing with cassette-based portable studios as a youngster, I can only imagine how much I would have drooled over the features and quality of today’s digital devices. Features like built-in effects and compression, automation, recall, archiving, rudimentary editing and MIDI control are all available at lower price-points than ever.

The VF-16 is no exception. The engineers at Fostex have squeezed all the above and more into a deceptively small package. The result is a multipurpose unit aimed squarely at jingle and songwriters, bands and small project studios.

FEATURES

The VF-16 ($1,399) is a digital multitrack recorder and mixer with six channels of 1/4-inch unbalanced inputs and two channels that offer both unbalanced 1/4-inch and XLR input, for a total of eight. These last two channels are also equipped with TRS (send and receive) 1/4-inch inserts and menu switchable phantom power. Each analog input features its own preamp with trim knob and peak light.

Digital inputs are optical, and they are switchable between S/PDIF (IEC 60958) and ADAT lightpipe. The lone aux send jack doubles as sends 1 and 2 (with send 1 as the tip and 2 as the sleeve). There are no returns.

As mentioned above, good design of these units depends on making artful tradeoffs, and Fostex has made some interesting choices in this department. While the numbers of analog inputs and outputs are limited (and, at –10 dBV, are not compatible with most pro gear), the company has included only optical digital I/O, usually found on more pro-oriented equipment. This slightly bipolar trend continues as we move through the feature list.

Rounding out the I/O are MIDI in and out, and 1/4-inch jacks for monitor output, punch in/out and headphones. The lone analog master bus outputs are on RCA jacks. This means the only way to play your mixes is through unbalanced connectors or to a device with the optical digital interface. The Fostex does thoughtfully provide a 25-pin D-sub SCSI connector for backing up audio data to an external SCSI device. This feature allows the user to take the raw tracks in WAV.

Within the unit, recording takes place on an internal 3.5-inch EIDE hard drive. All audio data is saved as uncompressed 44.1/16-bit data in a Fostex proprietary format (FDMS-3). The unit can, however, transfer files to the external drive as either FDMS-3 or WAV. This is where this unit really makes a case as a professional device — good resolution uncompressed audio with the ability to offload data to standard media.

You can record and play back up to 16 tracks simultaneously, limited of course by the number and type of inputs. The included hard drive yields approximately 15 hours of mono track time. A/D is accomplished with a 20-bit, 64X oversampling DAC and then dithered to 44.1/16 bits. Once your audio is in the box, all operations take place in the digital domain.

The front panel has 16 channel faders and a master fader, standard tape deck controls, and a large jog/shuttle wheel that doubles as the main data entry device. Features are accessed via momentary buttons, all of which are lighted from the rear to indicate status — a nice touch. Better yet, the channel mute/select buttons change from orange to green to red and can flash to indicate various configurations.

The LCD screen is small, about 2 inches by 3 inches, and its default page has tiny meters for each track/channel and the output bus. With the press of a button, the screen switches to any of a myriad of menus to adjust parameters and view information.

On the signal processing end, there are two effects busses — the first with 28 reverb presets, and the second with the same reverbs plus additional effects such as delay, chorus, flange and pitch shift. Compression is included, but it can only be assigned to the master bus and to Channels 13 through 16, presumably for submixing/bus mastering. Each channel has its own pan and EQ controls. All these are accessed in standard digital board fashion by choosing the parameter, selecting the track and tweaking away.

In addition to the standard transport controls you can set up to seven locate points, although some of these do double duty as edit points. The scrub function allows you to view a waveform for a specific track and fine-tune a location with the wheel. Editing is by simple cut/copy and paste, with an option for repeated pasting to set up loops. Tracks are easy to reassign and, using the bus record, you can bounce tracks to submix or to run a final mix back onto open tracks. Fader levels and mutes can be saved as scenes, and scenes can be saved as events, for effective automation, although dynamic fades are a little tricky under this regime.

The VF-16 has a lot of features for syncing up with external MIDI gear and can either generate or slave to MTC as well as MMC. In addition to absolute time or MTC, the unit’s time base can also be set to bars/beats mode and there is a built-in metronome.

IN USE

With all those features, just getting started might seem a little intimidating. Unfortunately, the manual appears to have been translated into English from another language, perhaps one not of terrestrial origin. Especially for a consumer unit like this, a more linear and less jargon-laden approach to getting started would be helpful. The learning curve is fairly steep; nearly all functions are accessed by navigating through menus, which are often confusing. (In the U.S., Fostex has addressed the manual deficiencies by releasing its own "Quick Start Training Guides"—Ed.)

Once you’re up-and-running though, the operation is speedy. If you’re used to tape-based recording, you will definitely not miss waiting for the tape to wind. Once learned, the procedure for assigning inputs to tracks is comprehensive.

The recorder excels as a scratchpad for songwriting or tracking. The built-in preamps were quiet and faithful, although the amount of headroom is a little low. Overall sound quality is very good, and there is more than enough storage space for most applications. In general, the unit is transparent and quiet.

EQ and effects are easy to manipulate, but the EQ section is where I first started to second-guess some of the tradeoffs made in the design of this unit. The EQ has a very informative display with a graphic response curve. Controls are for three bands — the high and mid controls are almost fully parametric, with controls for level, frequency and Q.

The low control is a HPF, with only a level control. The drop-off starts at 400 Hz, an extremely odd, and high, frequency choice. A low shelf is most often used for eliminating rumble and noise buildup across tracks, but this cutoff was too high to avoid getting into frequencies I wanted to keep.

Compounding the problem, neither of the other bands can be adjusted below 500 Hz, although both can be set all the way up to 20.2 kHz. How do you, for example, add a little 80 Hz to the kick drum? Apparently you don’t.

On the effects front, some of the reverb patches sounded great and others sounded cheap and digital. The magic adjustment (the "suck" knob if you will) turns out to be High Ratio control, essentially a high frequency damper. With this adjusted downward, some of the spaces sounded very realistic, and the NormVocal preset sounded positively dreamy. Other effects also sounded very good, especially the pitch transposition and delay. Keep in mind that all the effects are on busses, so a little creativity is required if you want to remove the direct signal. Luckily, each channel send can be toggled pre/post fader.

The editing functions are extremely handy, although, again, a bit confusing. To cut and paste you must find and assign markers to the clipboard in and out points, then find the insert point, set another marker, and then go through a couple steps to execute the edit.

The combination of the large jog wheel, wave display and audible cuing makes it possible to do some pretty tricky edits. Also, if you’ve been working on your song in bars/beats mode, you can quickly do some simple sampling and looping.

Automation is well implemented — simply a matter of setting up scenes and saving them, more or less on-the-fly. Fader and mute data are saved and recalled in real time, with up to 99 events per program. Which brings up the last of the inexplicable missing features. There is no solo button anywhere to be found, which makes auditioning EQ, effects or inputs very difficult. I find this and the odd EQ implementation puzzling. Being a digital mixer, these could be rectified with some programming. Perhaps Fostex will do so for the next software revision?

SUMMARY

The VF-16 is an impressive tool for writing songs, tracking demos and even recording live shows. It sounds great, it’s very small and lightweight, and it lets you do some things that have only recently come within the reach of semipro gear.

Certain computer-based packages, such as the Digidesign Digi 001, are very competitive in terms of features and price, but as a standalone, the VF-16 is a very useful tool. I would recommend it especially for songwriters, as it is inexpensive and simple enough to not interfere with the creative process, but flexible enough to be able to do some advanced work.

The clean operation and uncompressed audio are great too, since you always have the option of keeping tracks if you go into the studio to rerecord; we’ve all been in those situations where the demo had a certain feel that was hard to duplicate.

The compromises? Most of my real criticisms of this unit are things that would not cost too much to include. For example, the poorly adjustable EQ, no solo button and badly written manual. Some of these can be frustrating. I hope Fostex will address these in future versions of the product.

Although these issues make it less suitable for a studio-type environment, that’s not really what the recorder is for. It’s a solid musical scratchpad, and, if you need to be able to do something advanced, you probably can. The VF-16 is a worthy portable, all-in-one solution for songwriters and home recordists.

Value outshines quirks in Fostex’s latest multitracker.
by Steve Broderson

When Fostex made the leap from cassette-based multitracks to digital audio recorders, it didn’t forget the legions of songwriters and other musicians with big dreams but limited budgets. The company’s previous models often emphasized low cost and flexibility over bells and whistles, and this approach is clearly evident with Fostex’s newest offering, the VF-16 digital multitracker. With two rows of 60 mm faders, two built-in effects processors, a 5.1 GB internal hard drive, a SCSI interface, variable pitch control, a jog/shuttle wheel, and a modest $1,499 price tag, the VF-16 will undoubtedly raise some eyebrows.

The VF-16 provides 16 tracks of uncompressed digital audio along with 8 “virtual” tracks for a total of 24 tracks per project. (The virtual tracks serve mainly as holding places for alternate takes.) With many digital multitrack recorders, you can easily swap virtual tracks and primary tracks, which makes cutting, copying, and rearranging data simple. The VF-16’s implementation of this feature is a bit different. Its virtual tracks (17–24) are swappable with primary tracks (1–16) by means of the Track Exchange command, but you can’t edit or hear a virtual track until you exchange it with a primary track. That limitation makes the editing process more awkward than it could be. With a little care and planning, however, you shouldn’t have much trouble.

The VF-16 uses a 20-bit A/D converter and a 24-bit D/A converter, but the output is limited to 16-bit, 44.1 kHz audio. To store its digital information, the VF-16 uses Fostex’s proprietary FDMS-3 format, which increases hard drive efficiency by optimizing data on the fly. Recorder status, mixer status, waveforms, menus, and various other functions are displayed on a backlit, 64 5 128-pixel LCD screen. Some of the top-panel buttons illuminate or flash to let you know what mode you’re in, and the large jog/shuttle wheel is a big help when editing.

INS AND OUTS

You can record up to 8 tracks at once using the 8 analog inputs, or record 16 tracks at once using the onboard ADAT Lightpipe interface in addition to the eight analog inputs. Two of the eight unbalanced input jacks are doubled by balanced, phantom-powered XLR jacks. These channels also include a TRS insert jack for adding an outboard device like a compressor/limiter. The phantom power is turned on from the Setup menu, but the VF-16 doesn’t retain the setting when you shut down. Each analog input channel includes a Mic/Line trim pot and an LED clipping indicator. I used my Rode NT-1 to test the VF-16, and I found the mic preamps to be detailed and transparent, although a bit quirky in their gain stages. I noticed a smooth, gradual gain rise from line level to about the four o’clock position. (The pots are calibrated with dots rather than numbers.) From four to five o’clock, however, very slight adjustments made big gain differences.

Although the mixer is flexible in other areas, its primary shortcomings are its lack of auxiliary returns and the inability of the line inputs to function as aux inputs at mixdown. That means if you’re bringing in signals from external effects or MIDI gear, you’ll need to sacrifice mixer channels. Submixing your outboard gear to a stereo pair still leaves 14 channels, but with the recorder’s two aux sends per channel and full MIDI sync features, the lack of aux returns and inputs is puzzling. Another bit of inconvenience is that the onboard Metronome click is automatically routed to track 16. If you have anything on that track, you have to move it, deselect it, or do without it.

Two recording modes govern your tracking: Direct and Bus. In Direct mode the signal bypasses the mixer and is routed through the trim pot directly to the recorder on the corresponding track. You can use Direct mode to record through eight inputs simultaneously. Bus mode offers greater flexibility by letting you send any input through the mixer to any track. With Bus mode you can record multiple inputs to two tracks, and you can bounce tracks. The VF-16 manual suggests that Direct mode results in better recording quality because the signal doesn’t pass through the mixer section. Technically speaking, that may be true, but I couldn’t hear any difference. If your hearing is especially acute, you can always do your tracking in Direct mode and use the Track Exchange function to send your recording to whichever track suits you.

Generally, getting from input to recorded track was pretty straightforward, but some operations were less intuitive than they could have been. For instance, Input Source is not the same as Input Select. You must activate both and engage Record to hear your input. Additionally, you must turn up the fader to monitor a recording track. Logic and previous experience would suggest that’s a sure way to get feedback. This could be a source of frustration for beginners who will no doubt be drawn to this unit because of its affordability. Help is available, however, in the form of two thoughtfully prepared Quick Start guides (in PDF format), downloadable from the Fostex Web site. They turn the somewhat daunting language of the owner’s manual into an easy-to-understand walk-through of Direct and Bus recording options.

Like most similar devices, the VF-16 generates sync signals. MIDI Clock (bars/beats) and MIDI Time Code (MTC) are both supported, and in my road test with Emagic’s Logic Audio, both methods worked flawlessly. You can assign a tempo and time signature when using MIDI Clock/Song Position Pointer, and you can set a global preroll time before a locate point. MIDI Time Code options include an offset and a frame-rate selection. The VF-16 can also act as a slave to an external MTC signal.

MIXING TOOLS

A 3-band EQ (parametric High and Mid with shelving Low) is available for each input. High, Mid, and Low settings are graphically represented on the LCD screen, and each band has its own button for speedy access to its parameters. Unfortunately, you can control the frequency and Q setting (the width of your EQ curve) only for the High and Mid sections. The Low section simply provides gain boost or cut. Because proper low-end control can really make or break a mix, it seems a shame there isn’t more flexibility in this section. A built-in stereo compressor (with control over threshold, ratio, attack, and gain) is assignable to tracks 13 and 14 or 15 and 16, but only with the EQ turned off. You can, however, combine the EQ with a second stereo compressor dedicated to the Master output.

The VF-16 has two independent built-in processors; each channel has two internal effects sends along with the two aux sends. The first processor provides a bank of 28 reverbs along with a few delay/reverb combos. The assortment of halls, auditoriums, plates, rooms, and other reverb types employs a new Fostex technology dubbed Advanced Signal Processing. The company claims that this feature significantly improves processing efficiency and provides greater detail for early reflections. After using the VF-16, I have to admit that the reverbs sound lush and natural with smooth decays and plenty of presence.

The second effects processor provides the same 28 reverbs, along with ten extra effects: delays (including tempo delays), chorus, flange, and pitch shift. Though the number of effects isn’t huge, the VF-16 covers the most-used categories, and each effect has a full array of editable parameters. Unfortunately, no storage space is provided for saving your customized variations. As I mentioned earlier, the aux sends are a nice touch, but their potential use is hampered by the mixer’s return limitations.

One great advantage of using a digital mixer is that you can store snapshots or “scenes” that recall a particular configuration. The VF-16 provides this feature and a lot more. All level, pan, and effects settings can be saved along with a title to any of 100 Scene Memories. These scenes can be recalled directly with the push of a button, or automatically during playback as part of a scene Event Map. It’s not quite the same as “flying faders,” but you can automate changes for a hands-free mixdown.

The procedure is easy. First, you define a separate scene for each change you wish to make. Then you create a scene Event Map by entering locations (with the jog/shuttle wheel) to show where the changes are to occur. The Event Map sequences are editable too, in case you want to hear your mix another way. This is an impressive feature considering the modest price of this unit.

SLICE AND DICE

VF-16 users can section off areas of a track for editing and manipulation by using one of seven Memory buttons. The standard Cut, Copy, Paste, Erase, and Move commands are provided, along with a Clipboard to which the audio is sent before it’s pasted or moved. With a couple of clicks, you can hear just the portion you’re about to send somewhere (or obliterate), which is a handy double-check feature for editors with itchy trigger fingers.

The Memory buttons also let you mark sections to punch in, repeat, or automatically return to, and by pressing the Shift button, you can set seven regular marker points to quickly tag any place in your song. Because the seven keys serve double duty, some extra button pushing is involved. Pushing a Memory button doesn’t simply take you to a location; you must hit Locate, too. Moreover, the Locate buttons aren’t lit like some others, so you can’t tell at a glance if you have points set. An Event Memories display lets you view and edit all your locate points, however. You can also locate precise audio points with the Scrub feature, which includes a waveform display and audio feedback.

Editing is generally easy and flexible, although you get only one level of Undo. This saves Event memory and increases efficiency, but you’d better like your edit before you hit Record again, because you can’t go back.

The VF-16’s owner’s manual has a few shortcomings. Aside from its lack of an index, the 121-page manual, translated from Japanese, has some serious readability problems. Fostex claims that it’s working to improve the instructions, but I have no idea what this ominous warning means: “In the case whereby data registered in the Clipboard is the actual sound point and head of the measure is behind this, then even though you attempted to paste this head of the measure in alignment with this previously head, it will be pasted off alignment by this procedure due to the Clipboard In=Align Sel function.”

BACKUP PLAN

Changing clients as often as I do, I can’t let a hard drive’s contents pile up for long. The VF-16 comes standard with a SCSI interface and can back up files using optical S/PDIF (switchable to ADAT). Unless you have an ADAT Optical-equipped audio card for your computer, the SCSI option is the best way to go. The S/PDIF approach basically dumps two tracks at a time into your digital recorder in real time. That means waiting eight times as long as your song if you’ve recorded all 16 tracks. The SCSI hard disk route lets the VF-16 send all the data at once to disk if you initialize your media with Fostex’s proprietary format. You can also save songs to a DOS-formatted drive as WAV files. This method is handy because it lets you easily manipulate your sound files in an audio editing program. It also lets you save all scene settings and offers the option of saving all or only certain tracks (including virtual tracks).

For speed and convenience, many users will choose to archive their VF-16 recordings with a high-capacity removable-storage device like an Iomega Jaz or Panasonic DVD-RAM drive. But if you have an Iomega Zip drive, the VF-16 can also save to multiple disks. Though not as convenient as dumping everything to a single hard drive, the lower cost of Zip disks and the huge installed base of Zip drives makes this an attractive alternative.

If your studio has optical and coax digital connectors, you’ll want to check out Fostex’s COP-1 coaxial/optical converter box ($94). I used it to get the VF-16’s signal to my sound card’s coax inputs and vice versa. Digital output from my Mac’s audio card and from my Johnson Amplification’s J-Station guitar modeling preamp flowed effortlessly into the VF-16. You can route digital input to any two tracks using the Setup menu.

To expand your recording capacity, Fostex has made the internal EIDE hard drive easily swappable with larger-capacity drives. Although the company doesn’t officially recommend taking on the job yourself (it voids the warranty unless Fostex makes the swap), the manual offers an illustrated step-by-step guide to replacing the hard drive.

FINAL TAKE

I used the VF-16 during the review period for on-location recordings, studio tracking, and audio transfers between the recorder and my Mac. It performed well in these settings and ought to make a worthwhile investment for bands, songwriters, or project-studio owners.

Fostex has done an admirable job of capturing the middle ground in the digital-multitrack arena by offering an attractive balance between price and power. With a little shopping, you could add a removable storage drive and an outboard multi-effects unit and still keep the price tag around $2,000.

On the flip side, the VF-16 could stand a software overhaul to make it more flexible and user friendly. According to a company spokesperson, an update may soon be available through Fostex in the form of a flash ROM upgrade through the SCSI port. Even in its current state, though, the VF-16 offers a lot of recording power at a very reasonable price.

User Review

by Chris R.  (c h r i s r AT a u s t i n DOT r r DOT c o m)

I should mention, I’m not a professional in the music industry or a recording expert. I’m a guitarist interested in home recording and MIDI, strictly for the purpose of developing my own projects (primarily for my own edification). I’ve used a Yamaha MT-100 4 track for several years and was waiting for digital multi-tracking to reach a feature/price point that would justify upgrading. Really, I was interested in an 8-track but when I heard the VF-16 was being released at a price point comparable with other 8-track units (and with a ton more features) I decided to wait. Glad I did, because the unit appears to suit my purposes exactly.

Okay, so here’s what I think of the unit after three days:

Positive:

  • The sound quality is pristine.
  • The programming and controls are fairly straightforward (once you get past the learning curve, see comments on the manual below)
  • The display is very well organized for the various functions
  • The on-board effects sound great (although, I haven’t had a chance to play with anything except the reverbs)
  • Built-in compression
  • EFX inserts on two tracks
  • Phantom power on two tracks
  • MIDI slave and master for computer control (haven’t had a chance to use this yet but I will be making use of it in the near future)
  • Trim control for each channel
  • Copy/Paste on-board editing with Undo
  • Export to .WAV - you can then load the individual .WAV files (one for each track) on you computer and edit them with Cool Edit (or whatever) then re-import them back to the VF-16. Very cool!
  • Optical DAT and SCSI interface
  • Light, compact chassis -- well designed lay-out of controls
  • The black chassis is a big improvement over the former white (IMHO). At least now it matches the rest of my equipment
Plus a bunch more features I haven’t had a chance to even look at.

Negitive:

  • The manual is, uh, not good. Specifically, why in the world would they put the section on creating a new program (the most important factor to somebody first learning the unit) on page 59? Plus, the way it is laid out, it simply takes each one of the units sub-systems and explains in considerable detail what they do and how they operate. Fine, but this approach doesn’t do anything to help the user understand how they inter-operate and relate to each other. It took me several hours of reading the manual and playing with the unit to make my first direct recordings (I’m still trying to figure out the Buss recording mode). Call me dense, but like I said, I’m not a music professional or recording engineer, I’m a home recording enthusiast, which is the market segment this unit was developed for. So the manual should be targeted accordingly. Suggestions (for any Fostex reps out there to pass along): 1.) Include a "Getting Started" addendum to the manual. 2.) Include a chapter that does a "walk-through" of different recording scenarios (I know, there are some in the existing manual but they should be a lot better). A short video (perhaps on CD-ROM) that does a walk-through of the units sub-systems would be a huge asset.
  • Operation of the unit is NOT intuitive. Expect a learning curve of several days depending on how much of the feature set is important to you.
  • The display is difficult to read at a angle > than about 45 degrees. I propped my unit up in the back about 2 inches and now all is well.
  • I can’t find a way to auto-load a scene with a program. Maybe I’m missing something (not unlikely considering the manual). Hope there is a way because it’s very annoying to have to manually scroll through multiple scenes for each project
  • There is an audible "whirring" from the HDD. It is not bad enough to pickup on recordings (even with the mike right in front of the unit) but it deserves mention.
  • The unit as it was shipped to me had slightly uneven feet (wobble). A friend at work who ordered one the same time I did (and has since received his) reported the same problem. Again, nothing major, but it deserves mention
  • My unit didn’t come with a warranty registration card.

So, to summarize, most of the negatives are fairly minor annoyances (except the manual, which could REALLY use improvement). Overall, I’m quite pleased (and impressed) by the unit. I keep discovering more and more capabilities and it has opened up a ton of new options for me.
