Cheetah MS6 Project Machine

“Cheetah MS 6 (Matrix 1000 Style Multi timbral Analog Synth). Went to switch this old beauty on today and it is unresponsive and I can’t remember why. Was working. Display did something weird. Someone looked at it? Too old and deaf that Ableton isn’t way more convenient however good this sounds. Condition is “For parts or not working”. Dispatched with My Hermes or Collect +” Click here to visit listing on eBay

“This one was from a bedroom storage, never gigged, never in a studio. At 40 years old it has some obvious scratches, some dings, a missing button (easily replaced), the LCD is loose, and it shows just how usable this classic is. Please see photos.”

It has the same chips (CEM 3396) as the Oberheim Matrix 6 and the Oberheim Matrix 1000, but it is multi-timbral!!!Programming is possible from the front panel, as well as via MIDI editors. The auction includes only the device.” Click here to visit listing on eBay

“This synth was recently serviced, nee internal battery, new MAAD firmware installed (google search it and you’ll find the page with upgrade info) which drastically expands its CC controllability for easier editing and fixes some known bugs.

Like most of the cheetah rack synths they suffered from poor paint quality and has a little bit of rust here and there. Doesn’t effect the synths performance/functionality. See photos for details. This is a 110V unit. Item will be shipped via USPS or FedEx and insured for the sale value. Sold working but due to its age will be sold as-is no returns or buyers remorse. It pains me to sell this piece as it’s really one of the best sounding poly synths I own. Really rich tone. I’ll find one again some day.” Click here to visit listing on eBay

“For sale my classic and much loved MS6.
Cheetah MS6 6 Voice Polyphonic analogue Rack Synth. (as used by OMD and Rick Wakeman).
Plus owners manual!

One of the warmest sounding synths out there, 2 oscillators per voice, each with their own Curtis filter + 6 note polyphony.

Battery saves presets and parameters just fine.

Good working order with a couple idiosyncrasies. and a few light scratches as you might expect from a rack of this age..

I’ve been holding onto this synth for 20 years but it’s not seen much play in the last 12 years, just been safely stored away in my home studio.

There are a couple of things I should point out:
– She’s missing a button on the front in position 5. There’s one on ebay now for $8.50 (search ‘Cheetah – MS6 – Small Push Button’). That said, the bank changes can be controlled via midi of course which is how i worked so this did not bother me.
There’s also an edoitor programme available here: that can be used to program sounds on your computer, (along with many other resources).
– I believe that originally the multitimbrality of this synth meant that you could assign a different midi channel to several voices. I don’t believe this is the case here (at least i con’t know how that works) and frankly I can’t really imagine you wanting to. The beauty of this beast is in the layered unison of voices to create incredibly rich analogue sounds. The synth only has the one audio out so if you want to add effects in the mixer you’ll only ever be able to record the one track at a time anyway (I’ve not met anyone that uses it otherwise). It shines best when all the polyphony is being use on the one voice (there are loads of amazing presets stored in several banks)
– Lastly the the LED display glitches a bit sometimes when the unit is plugged into the mains but is turned off. Behaves perfectly when turned on.

ADDED NOTE: Since listing the unit has recalibrated and the Led display is behaving as expected when turned off so this issue may well be mute! ” Click here to visit listing on eBay

– Analog monster, sounds like a Sequential Prophet
– 6 note polyphonic with 2 oscillators per note
– Multi timbral… use as a poly, or 6 monos on separate midi channels! Or even say a 4 note poly with a bass and a lead!

This has fully working CEM chips. Some I’ve seen, seem to work, but have some weird missing notes/note stealing due to faulty Curtis chips – not this one.

A few knocks and paint scrapes on the top, but otherwise in fine condition.” Click here to visit listing on eBay

When I last used it, it was producing rich, fat, silky sounds!

Sadly it’s not working. It powers up, the display lights up but it won’t produce any sound? MIDI fault? Synthesiser fault? Output amp output? I’m sorry, I have no idea. ” Click here to visit listing on eBay

For your consideration is a used Cheetah MS6 module in great condition. Unit sounds clear and is in perfect working order as far as I know, no hum or dead voices. I have used this module only a few times in the years I have owned it. (Had two MS6’s, the other unit was not in excellent condition so I used it more often before eventually selling it). Original manual is included. This one is set up for the North American voltage, 120v! ” Click here to visit listing on eBay

For sale is a Cheetah MS6 6-voice multitimbral analog synthesizer module. The Cheetah MS6 is a beautiful sounding synth that uses CEM3396 synthesizer voices. This unit had the power supply rebuilt and the firmware was upgraded to version 9.0, which supports MIDI sysex implementation (necessary if you want to program the synth using an iPad or knob controller). Everything is working great in this unit. Cosmetically, the outside case has a few scratches, which is expected of rack gear from the early eighties. The unit has a clean bill of health. ” Click here to visit listing on eBay

Up for sale is my rare Cheetah MS6 analog polyphonic/multi-timbral synthesizer. This is a six voice dual DCO synthesizer (12 DCOs total) with analog 24db/oct filters with resonance control, using CEM 3396 chips which are the same as you find in some Oberheim synthesizers. It has the Maad firmware mod which adds programability using MIDI CCs, extra waveshapes and many more features (see

I’ve owned it for a few years and it has been one of my favourite synthesizers but since getting into modular synthesis alot of my old gear is not getting much use and I need the space so I’m selling them. It is in great cosmetic condition with barely any marks on the front panel, the screen and all the buttons work well and I have tested the MIDI and the audio output and checked the calibration of each CEM 3396 – everything is 100% functional. It has a UK plug but the lead is quite short. If you are interested in this you may also be interested in my Cheetah MD16 drum machine – see my other items.” Click here to visit listing on eBay

“Cheetah MS6

great synth.

slight damage to left rack wing see photos, I think this has slightly affected the very leftmost led also it flickers a bit during use.

writing is a bit worn on top of case also.

100% fully functional though.

+ modified grounding ensures no electric shocks from this one, (common problem with these synths)

also midi grounding hum mod made aswell to ensure no ground loop created through midi IN

+ battery replaced with a brand new one to reduce the risk of battery leaks/corrosion for another 20 years.” Click here to visit listing on eBay
