Ensoniq SQ-80 Project Machine

“Does not power on, the screen blinks briefly, but it does not stay on nor boot

Clean inside, no signs of damage that I can see

Outside of case, keys, etc are all in great cosmetic shape, the two left side top case fasteners have slight damage inside, but case stays closed fine

PSU has been re-capped, but not by me so I do not know it’s history” Click here to visit listing on eBay

Ensoniq VFX SD

“Ensoniq VFX SD Synthesizer. Condition is “Used”. I bought this from an estate sale. It does not have a plug so I have no way to test it to know if it works. Look at the pic there is a piece of plastic that is missing should not effect it playing” Click here to visit listing on eBay

Ensoniq SQ1 Plus

“All keys, buttons, sliders, pitch bend, mod wheel, display, etc working perfectly.

Battery changed 3 April 2021. The 2032 battery has a holder so no soldering required, just an easy swap.

No original manual, but I include a printed PDF version in a binder.

There is minor cosmetic damage, the worst of which is a gouge on the front panel and some other minor scratches here and there, including one of the keys (so minor it was not possible to make it visible in the photos) and a very tiny crack on the display (see pics), but overall very good condition for the age.” Click here to visit listing on eBay

Ensoniq SQ1

“Hi guys. I’m selling my Ensoniq SQ1 Synthesizer. One of the great vintage synths of from 90s in great condition. The display is a bit dim, and the keys have a slight yellow tint due to it sage, but works fine. Ensoniq are well known for producing top quality products, and this model is no exception.”

Ensoniq SQ1

“You are viewing an Ensoniq SQ-1 synthesizer in mostly working order!

This is an awesome keyboard which really I want to keep and play with, but alas, I can’t keep everything!

I’ve tested this with the headphone jack and everything sounds brilliant. I’ll try and get round to trying the other outputs in the next few days, but if you need to check the midi you’ll need to bring your own equipment as I’m only a novice.

Screen display has a decent brightness to it and overall cosmetic condition is good minus the two snapped keys.

Cons – bottom key is dead and there are two buttons which have been pushed in which don’t function.

Otherwise, you have yourself a great working synthesizer on your hands at a bargain price. I can recommend a fantastic affordable repair guy if you want the bottom key and stuck buttons looked at.” Click here to visit listing on eBay

Ensoniq MR Rack

“Ensoniq MR Rack. Condition is “used”. The internal battery was just replaced. There are some scratches on the top and bottom of the unit. The rack ears are slightly bent, but still totally functional. A complete print out of the manual will be included. CD rom will be included as well. The unit sounds amazing. Ships with AC cable.” Click here to visit listing on eBay

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

Ensoniq SD-1

“The synth is perfectly useful as a midi module and as a keyboard and “left-hand” controller, for this you can use any suitable sequencer or editor software (such as SoundDiver which was used for testing). The problems with the synth that can be completely ignored in a studio setting but are important for a live/standalone use are all in its front panel: buttons cannot be used for control without a computer software and data slider is missing its “handle”(although data entry buttons on the left double its function, so it can be ignored if working directly with synth). These front panel physical response problems can be repaired later if desired, or just continue to use it as a module/controller with a computer as described. I have now also found the data slider’s plastic cap, so I will send it together with the synth.” Click here to search for synths on eBay

Ensoniq ESQ1

“Ensoniq ESQ-1 Wave Synthesizer- Partially Working. One Octave NON-FUNCTIONAL. Condition is “Used”. This is the METAL case ESQ-1. Rom upgraded to 3.50. New backup battery installed November 2020. Includes 1 sound cartridge. As an extra bonus some labels were installed on the keys so you can navigate your way around those tricky notes.

There’s nothing better than a metal keyboard case because it’s tough and can take a beating so if you’re using this on the road you’ll be pleased with the durability.

The factory screws used to secure the top and keyboard have been replaced and half are missing. One of the top screw sockets has broke (see photo). As mentioned in the headline one octave of the keys are non-functional. This is the second octave section. Except for those 13 notes the keyboard works just fine so if you are a right handed soloist, you will be a very happy with the sounds.” Click here to search for synths on eBay

Ensoniq ESQ1

“Works well.
Occasionally flashes a battery warning which is remedied by replacing or re-seating the calculator battery under the lid and it works as normal.
All other functions and keys etc work correctly. Includes a sound cartridge for storing patches.
In great cosmetic condition.

This is also the nicer (in my opinion) black metal version, not the later plastic one.” Click here to search for synths on eBay

Ensoniq Mirage


This is a great vintage Ensoniq Mirage DSK8 DSK 8 Sample Playback Synthesizer . A Classic. Loads, samples and plays back sounds well. A great 8 bit sampler. Adds character to sounds unique to itself only. This is the model with the better feeling Fatar Keybed. The keyboard works well. Ships Well Packed and Insured!” Click here to search for synths on eBay

Ensoniq Mirage DSK

“Excellent condition, should have cleaned before photos just needs a dust but it has been covered by a sheet for protection.
Lots of sound disks including original Ensoniq disks that sell on their own. Has all the detroit and house presets used by Derrick May, Kevin Saunderson etc. But can also be mind blowing when used for its synthesis as appose to the sampler (check youtube).
Has a chip out of one of the keys (pictured) replacements are still available though fully functional as is.
No synth sounds like the mirage even with the lovely clones coming out nowdays it still has its own sound that adds so much feeling.” Click here to search for synths on eBay
