Akai EWI1000
A wind controller that asked players to unlearn everything their fingers knew - and rewarded the ones who did.
Overview
The EWI1000 is Akai's Electric Wind Instrument. It's a controller, not a synthesizer. On its own it makes no sound. It has to be plugged into something else, and in Akai's own ecosystem that meant the VX600, a programmable matrix analog synthesizer built to receive it. The manual for the VX600 devotes an entire section to the pairing. Reading it is the fastest way to see what Akai was selling: not a horn, not a keyboard, but a breath-to-voltage converter with a mouthpiece on one end and a multi-pin connector on the other.
The instrument connects to the VX600 through a dedicated multi-connector, using the cable included with the EWI1000 or an optional Akai EW-X70 extension cable. That single cable carries the breath signal, the bend and glide controllers, and the key data. Nothing about the EWI1000 is generic. There is no standard interface and no MIDI jack on the instrument itself. It speaks Akai's proprietary language to Akai's proprietary box, and that has shaped the used market for these things ever since.
The VX600 manual describes the breath sensor as the heart of the system. Frequency, tone, and volume all respond to breath pressure, and players can route that acoustic envelope to VCO frequency, pulse width, filter cutoff, resonance, VCA amplitude, LFO speed and depth, and FM depth. Blow harder and the tone brightens and the volume rises. Blow softer and it goes dark and quiet. The manual is direct about the payoff: using the acoustic envelope rather than the synth's own envelope generators produces more natural results and simplifies playing, especially for wind players, who already have a lifetime of breath control built into their muscle memory.
Akai also shipped the same control surface in a brass-flavored variant, the EVI1000, for valve players. Both connect to the same VX600 instrument terminal, both use the same extension cables, and both appear side by side throughout the documentation. Collectors tend to treat them as a pair.
Key Features
Breath Sensor and Acoustic Envelope
The VX600's front panel carries a BREATH ADJUST/SENSE control with two knobs. One sets the sensitivity of the EWI1000's breath sensor. The other sets the operating point that matches the individual player's breath pressure. Akai understood that a trumpet player, a saxophonist and a flutist all blow differently, so the instrument had to be calibrated to the human rather than the other way around. The manual walks players through the [L45 [EWI #1]] library tone as a starting point, instructing them to play while varying breath pressure and listen to how the tone opens up or closes down.
Because breath can be routed to so many destinations, the modulation matrix becomes the real instrument. Akai's own documentation includes a reference example assigning breath to filter cutoff at +32, VCO-1 pulse width at +35, and VCA amplitude at +99. It's a basic patch that gives the player dynamic tone color, harmonic movement, and volume from a single breath stream. The manual is candid that envelope-generator-based tones can be genuinely difficult to play from the EWI1000, and that this is not a malfunction.
Bend and Glide Controllers
Two more front-panel controls on the VX600 exist specifically for the EWI1000. BEND ADJUST/WIDTH offers a sensitivity knob and a width knob, letting the player tune how far a bend travels and how much physical input it takes to get there. GLIDE ADJUST/TIME does the same job for portamento, with sensitivity on one knob and glide time on the other. Akai put both on the synth's face rather than burying them in a menu.
Vibrato Control
A VIBRATE knob on the VX600 adjusts vibrato and tremolo when the EWI1000 is connected. The manual also documents a dedicated EW.VIBRAT modulation source, giving breath-driven vibrato a direct path into VCO frequency and pulse width. It's routed through the same breath signal rather than a separate LFO.
Connector and Cabling
The INSTRUMENT terminal takes the EWI1000 or EVI1000 directly via the supplied cable, or via the Akai EW-X70 (for the EWI1000) or EV-X70 (for the EVI1000) extension. The manual is explicit about which cable goes with which instrument, and the two are not interchangeable in Akai's own documentation. The VX600 also offers a VOICE OUT on a 13-pin DIN, an EXT IN, stereo line outs, a headphone jack, and standard MIDI IN/OUT/THRU, so the EWI1000's proprietary connection sits alongside conventional I/O for everything else in the rig.
Historical Context
The EWI1000 belongs to the mid-1980s, when wind synthesis was a genuine commercial category rather than a curiosity, and the period press covered it that way. Mix-Magazine (October 1987, p.244) ran the EWI1000 in its new products column, listing a 4kHz - 40kHz specification. That figure positions the instrument as a serious audio device rather than a toy. The same issue sits alongside other 1987 product announcements, which places the EWI1000 in the era when Akai was pushing hardest into electronic instruments.
Trade coverage of the period was consumed with MIDI and synchronization standards. Recording-Engineer (September 1987, p.59) devoted space to the emerging MIDI Time Code debate, noting that one manufacturer described it as "where things are going." The EWI1000's proprietary instrument connector sits in tension with that moment. Akai built a closed loop between controller and synth at exactly the point when the rest of the industry was standardizing.
The EVI1000 valve variant shipped alongside it, and Akai's documentation treats them as a matched set throughout. The VX600 manual's repeated references to "the AKAI EWI1000/EVI1000" - sometimes with OCR-mangled spellings like "EW11000/EV11000" - show how thoroughly the two were documented as a system.
Collectibility & Value
The EWI1000 has one specific problem: it needs a VX600 to make sound. The instrument has no onboard tone generation and no standard MIDI output on the unit itself, so a bare EWI1000 in a case is a controller waiting for a very particular partner. Collectors chasing the EWI1000 should expect to hunt for both pieces, and should verify that the proprietary connection cable comes with the instrument. Akai's documentation is clear that the cable is instrument-specific, and a missing cable turns a working controller into a display piece.
The VX600 side carries its own maintenance concerns. The synth is a programmable matrix analog design with battery-backed internal memory, and the manual's specification notes that stored programs depend on that battery. A VX600 with a dead backup battery will have lost its factory library and any user patches. The manual also warns that some factory tones suit keyboards rather than the EWI1000, so a buyer can't assume a restored library will play well from the wind controller. Akai's own text advises players to audition tones and build their own if the factory set doesn't suit the instrument.
Specific market prices and documented failure modes for the EWI1000 aren't established in the available documentation. Complete systems with the correct cable, a working VX600, and a healthy backup battery are the ones that hold value, and incomplete ones are parts. Buyers should ask about the cable first and everything else second.
