Alesis Quadrasynth

“Synthesizer is working and tested however has the following issues.

Only the lower half of keys is responsive. From middle C up makes no sound.
All keys respond over MIDI, so an external MIDI keyboard or sequencer will not have a problem sounding those notes.
The pitch / mod wheels rubbing against each other slightly.

The original QuadraSynth is very rare and hard to find since it had less than 2 years of production before the QuadraSynth Plus replaced it.” Click here to visit listing on eBay

Alesis Andromeda A6 Project Machine

“I am selling my (sadly) broken Alesis Andromeda synthesizer.

I had it repaired a few months ago and I was told by the technician that the main board needs to be replaced, but that he couldn’t locate one at the time. He replaced a timing crystal that was malfunctioning, but could find nothing else wrong with the unit.

Since then, I’ve seen a few spare main boards come up, but I wasn’t able to purchase them due to lack of funds and time to arrange repairs.

The plastic sides are missing, but other than that it is in good physical condition. Never gigged with it, it was kept in a smoke-free dry room. Worked fine when I left for a year long trip, but when I returned it had stopped working.” Click here to visit listing on eBay

Alesis Andreomeda A6

“Alesis Andromeda A6 Rare Vintage Polyphonic Fully Analog Synthesizer
Excellent Condition (See Pictures). I had this synth since 2005, it has never left my studio. Sounds SUPER AMAZING. This is the 16 voice analog monster you’ve read about. Many say this is the best and most powerful Analog synth of all time, even more powerful than the Moog One as Matt Johnson Jamiroquai states in one of his YouTube videos which you can look up and see for yourself. ”

Alesis Vortex Keytar

“Up for sale is a mint Alesis Xortex Keytar controller! I bought this brand new a few years ago with the hopes that I would be spending more time on keyboards than behind the drumkit….that didn’t happen. I had it out of the box once or twice to play with it a bit hooked up to my Roland JV-1010…worked fantastic! I just never got to the point where I played keys well enough to take this out and really utilize all the features. It comes with the USB cable, shoulder strap, Abelton’s Live Lite, and all documents. I will pack it well and and ship within 24 hours of payment (except Sunday). ” Click here to search for synths on eBay

Alesis Andromeda A6

“Alesis Andromeda A6 Analog Polyphonic Synthesizer. We’re trying to raise some money to help support our recording studio, and as a result, we’re selling some equipment. The synth is in really good shape and it works well. Two of the keys were replaced in 2013, and they are whiter than the other keys, but that is the only flaw. This is a beautiful instrument and a monster of a synth. I don’t have the original box but I do have a box provided by Alesis to fit the synth when it was serviced.” Click here to search for synths on eBay

I plugged it in for the second time this morning and it works like its supposed to still. ”

Alesis Andromeda A6

“You are looking at the auction for a used but in excellent great condition ALESIS ANDROMEDA A6, a modern true real Analog synthesizer that is no longer in production today. There were not many of them produced before Neumark acquired Alesis and discontinued production of this awesome analog synth. So you can think it as a polyphonic “Mini Moog” of modern times but with much more advanced features”
