Ensoniq SQ80

“Ensoniq SQ80 Cross Wave Synthesizer Keyboard. Original owner.

Keyboard works great – I’ve been using as a controller only. Includes one cartridge with two banks of sounds and FS1 foot switch.

I had the battery replaced two years ago. About 3 months ago started to show a warning message that the battery is low but I’ve left it on for hours and it has never failed. If needed, you can have the battery replaed for $60 or so but there doesn’t seem to be a need.” Click here to visit listing on eBay

“In excellent condition, I’d say. There are no glaring cosmetic issues and everything internally works just as it should.

The key bushings have been upgraded, ergo the infamous clacky keyboard is considerably less so. In fact, I wouldn’t call it clacky at all anymore. And the polyphonic aftertouch still works.

Bonus items included: An extra disk drive, should the one that’s in it ever fail; two disks with a bunch of sound banks on them, including some amazing Star Trek sound effects; A whole box of 10 unused DS/DD floppies, a user manual, a synth programming guide, and an expression pedal.”

“Here is my beloved Ensoniq SQ-80 that I bought in 1988. This revered keyboard is in good working order. It has a working hard drive, new battery, clear, bright screen and excellent sound. All keys work well, all buttons and sliders, as does the aftertouch. It is in good cosmetic condition, as well, with a few dings and scratches commensurate with its age and use. It has been played mostly in a small music studio and well cared for. A bound Musician’s Manual is available. ”

“Ensoniq SQ-80 with original manual, six voice cartridges and three blank disks.

Free Local Pick Up

I value the keyboard at $650 and the six cartridges at $350 hence my starting price. ( I do not want to sell anything separately at this time).

* Please read the full details of condition it all works but it has “personality”.
* Please ask questions if you have them.

It is fully operational including polyphonic after touch, has a new battery, all six cartridges work, floppy disk drive works , bender, mod wheel, SEQ, memory, all keys, etc.

It sounds wonderful.

Passed filter calibration tests (see photo)

Data slider was replaced and the new slider is 100% functional, but does not fit the old slider cap. (The broken slider and its cap will be included if you want to retrofit the old cap)

After its warmed up and running it turns on and off with no issues.

However, sometimes when its starting from cold, it has a boot “glitch”. Sometimes you power on and the screen does not come on, (turn off then turn on and your fine) sometimes you power on and it wants a soft reset (you do a soft reset, with power on hold down record and soft button and its back. The best voice to test its full functionality is internal 4, soft button 2 synbad. Play it and hold. press down, and you will hear the full poly after-touch.”
