Korg 01/W FD
A 32-voice workstation with a floppy drive bolted on - the version of Korg's AI2 flagship that finally let you save your work.
Overview
The 01/W FD is the disk-drive variant of Korg's 01/W workstation. The floppy drive is the whole reason this version exists. The base 01/W stored programs, combinations, drum kits, global parameters, and sequence data internally, but getting that data out meant relying on cards. The FD adds a real disk drive for saving your data. For anyone who sequenced seriously, that makes it a machine you can back up instead of one you can't.
Both versions share the same synthesis engine: 32 voices. Collectors argue about that voice count today. Thirty-two voices was generous for the period, but double mode, which is how you get layered or split sounds, halves your polyphony to 16. Owners who built dense, layered patches ran into that ceiling quickly. The tone generation method is listed as digital synthesis. That's the raw sample library the engine draws from, and it's why the 01/W series has its reputation for pianos and pads.
The keyboard has velocity and aftertouch sensitivity. Aftertouch on a 61-key workstation in this class mattered. It gets you vibrato, filter sweeps, or volume swells without reaching for a pedal. The service documentation includes a dedicated keyboard and aftertouch test. That's a diagnostic procedure, not a spec sheet, but it tells you the aftertouch implementation is continuous and full-range rather than a simple on/off switch.
Effects are handled by digital multi-effect systems. Programs number 200, combinations number 200. The sequencer is where the 01/W FD earns its "workstation" label: a 40,000-step sequencer. That matters if you're composing on the machine rather than just sketching. Forty thousand steps is a real song. Seven thousand is a demo.
The display is a full dot-matrix LCD with backlight. The resolution is modest by later standards, but it's enough to show parameter names, values, and sequencer data without cryptic abbreviations. The manual's diagnostic suite includes an LCD pixel test so technicians could verify the panel hadn't developed dead columns.
Outputs include main outputs plus headphones. The base 01/W has a different output complement. Control inputs include a damper pedal and assignable pedals. MIDI connectivity is standard. Power consumption is modest. Dimensions are typical for a 61-key workstation. The FD is slightly heavier than the non-FD due to the drive mechanism.
Inside, the 01/W FD uses a different main board than the base model. Both share several common boards. The FD's main board carries the floppy disk controller alongside the CPU and other supporting chips. The DAC is a dedicated chip. Wave ROM is spread across multiple chips. None of this matters until something breaks, and then the board number is the first thing you need.
The service manual's disassembly procedure is unusually detailed, with screw counts, part numbers, and a specific note that the FD requires removing the floppy drive assembly as step eight before you can get to the shield sheet. The drive sits in the way of almost everything. The manual also documents a noise and output test with specific regulation values. Signal levels at the main outputs should fall between 4.2 and 7.8 Vp-p. These are test tolerances, not marketing specs, but they show what Korg considered acceptable performance from a unit in good working order.
Period coverage of the 01/W line treated it as a serious professional instrument. A reader ad in Sound on Sound (1996, p.194) describes an 01W/FD as having 426 sounds, full editing, wave shaping, a 40,000-step sequencer, a disk drive, and "quality sound". The seller was asking under £1,000 and noted it was boxed as new. That 426-sound figure is higher than the factory 200 programs, which suggests the owner had loaded additional sounds from cards or disks. Another Sound on Sound reader ad from January 1996 (p.191) lists a Korg 01/W in immaculate condition, never gigged, at £875 or near offer. These are used prices from the mid-1990s, not original retail, but they show the 01/W line held value well in the secondhand market even as newer workstations arrived.
Korg's own advertising from the era, appearing in EQ Magazine (June 1992, p.70), billed the 01/W as "the 0 that started it all" and described the line as having evolved into "a full line of extraordinary music workstations." That's marketing copy, not independent evaluation. Still, Korg positioned the 01/W as the foundation of a product family, with the Pro and ProX extending the concept. The 01/W FD sits in the middle of that family: more capable than the base 01/W, less expanded than the Pro and ProX, but with the one feature that made it practical for serious work.
The 01/W FD's place in the used market today comes down to two things. One is the sound of the AI2 engine, which has aged better than many of its contemporaries. The other is the floppy drive, which is both the FD's defining feature and its most likely point of failure. Disk drives from this era need belt replacements, head cleaning, and sometimes recapping. When the drive works, it's a genuine asset. When it doesn't, the FD becomes a heavier 01/W with a non-functional bay. Collectors should test disk read and write functions thoroughly before buying, and anyone planning to use one seriously should budget for drive service or a floppy emulator replacement.
The 01/W FD is not the rarest Korg workstation, nor the most sought-after. It's the practical version of a well-regarded instrument, and the one people who actually used these machines tended to prefer, because saving your sequences to disk beats losing them when the internal battery dies. The AI2 synthesis engine, the 48 Mbit wave ROM, the 48,000-note sequencer, and the 61-key aftertouch keyboard are all part of the package.
