“240v. Slight bend on left rack ear.” Link
– 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.” Link
“Cheetah MS6 Analogue rackmount synthesiser module
Very good working condition
Has scratches where another module has stood on top
The mains lead has been cut and rejoined with a plug/socket for easy cable routing (behind shelves etc).” Link
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. ” Link
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! ” Link
• Excellent condition
• Tested and fully fully functioning
• User manual included” Link
“You are buy 1 (one) Vintage Cheetah MS6 MS-6 Analog Rack MIDI Synthesizer with 6 CEM3396 IC Wave form and shaper VCF VCA from Oberheim Matrix 1000.” Link
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. ” Link
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 http://www.maad.net/ms6/firmware_upgrade.html).
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.” Link
Comes with updated MAAD Rom.
Also includes sturdy hard-case suitable for any 1U rack equipment.
Unit powers up, but does not currently respond to midi and front panel buttons do not function. A bit beyond my ken to repair, but I’m sure someone out there can breath life into it! ” Link
“Unit comes complete with original users manual in good condition ( sellotape down the spine). Cheetah decided to silk screen the parameters list on top the module, this can be a bad idea once in a rack as you cannot see the list. I however have made a copy that will be sent with the unit, this is an A4 laminated sheet showing all parameters all laid out the same as on top the module.
This unit has all of it’s factory presets re-installed. Has a new hydride battery mounted on the main board. The are two brand new transformers to the original specification mounted inside the unit, this should give good reliable service for years to come. The unit has some paint damage at the front by a rack ear, there are other marks that have to be expected with a unit of this age. On the whole, a great piece of kit that will fail to dissapoint. A great example that could be a welcome addition to any computer setup. Unit requires 240VAC @ 50Hz, There is a switch at the rear allowing 110 VAC Operation.” Link
“I am selling a rare Cheetah MS6 6 voice multi timbral synthesizer. It will need to be serviced because voice 4 is faint and hard to hear. All the other voices come in loud and clear. Voice 4 was replaced so the problem might be a bad trace in the audio circuit from voice 4. I don’t read schematics and don’t have the money for a repair right now, so I’m going to let this go. All the patches are in place and sound great. MIDI is working fine. This even has the new MADD OS upgrade installed. The case is in rough shape, the finish is bubbled and rusted in places. Once racked it doesn’t look that bad. If you can read schematics and can follow the audio signal from voice 4, this looks like an easy fix. Otherwise, like me you might want to pay to have this serviced. ” Link
“This is a rare opportunity to buy a great bit of kit.
I was told that it has an Oberheim Matrix 1000 chip in it…as you can see from the picture one of the front buttons is missing but to my knowledge the rest of it seems to work…Happy Bidding!” Link
“Cheetah MS6 Multi Timbral Analogue Synthesiser Module I am unsure whether this works so I am selling as seen sometimes when you get 8 8 8 8 on the led screen other times you get nothing.” Link
This is a re listed item as there is a fault with the unit. The synth doesn’t play notes every half octave apart ie the 1st and 7th semitone are silent. This pattern is repeated across all octaves. The actual notes this affects seems to vary depending on the patch used e.g. C and F# in one patch, and perhaps D and G# for another. ” Link
“left rack wing slightly damaged but 100% functional. modified grounding + new battery.” Link
“You are looking at my Cheetah MS6 which is in great condition compared to many examples I have seen, comes with the original box and instruction manual, this beast gives you the oberheim sound. I’ve not really used it since I purchased it, everything works, sadly due to work commitments I don’t have the time to go on my equipment, hence the sale”
I have owned this from new since the 80′s. I had not used it for many years and recently dug it out of my old studio gear.
The case is not in the best cosmetic condition but the unit appears to function well. I installed the firmware upgrade from maad and also changed the battery.
The unit is much better than stock now and can be controlled from your DAW amongst other things.” Link
It’s been well used and its appearance reflects this. There’s a dent in the front panel (in one of the pictures) but it works perfectly and as you can see from the photos the legend on top is still completely legible.
I’ve owned it for what must be coming up to 20 years but not used it nearly as much as it deserves recently so have decided to sell it so somebody else can put it to good use.” Link
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.” Link
6 voice polyphonic
Programmable from the front panel
320 rom sounds
96 non ~ volatile RAM sounds” Link
” Vintage multitimbral polyphonic analogue synth, like a weirder cousin of the Oberheim Matrix 1000 with extra layering capabilities. This one has been fitted with a firmware upgrade that allows extra waveforms to be selected (combinations of the original shapes), so added tones are possible on it. I’ll send the original chip with the synth too, so you can revert it back to factory setting if desired.” Link
Works fine and sounds amazing.
No user manual included.” Link
“In one word – immaculate! This item was barely used from new in 1988 when given to me as a gift 10 years ago. I have used it twice and it has spent all other time packaged in its original box. Full working order and pristine – including original box and user manual. There is only a minor surface mark on top (shallow surface scratches) as show in the pictures but I confirm that this item has never been gigged or rack mounted at all.
You are unlikely to find an example in this condition very often!!!” Link
” Here we have a cheetah sound module that I’ve had in the studio for some time now, tons of sounds on there, too many to even try to list, no longer gets any use, so happy bidding and thanks for looking.” Link
“You are bidding on a Cheetah MS6 analog polyphonic synthesizer module. If you are looking at this, you likely already know what it is, but if not, it is similar to the Oberheim Matrix 1000, except unlike the Matrix 1000, the Cheetah MS6 is multitimbral! Has a few small scratches from being racked, but its in overall excellent condition, as you can see from the pics. Unlike a lot of these that sell, all of the writing on the top of the unit is in excellent condition, as you can see in the pic. Also, unlike most you see for sale, mine comes with the original manual. And perhaps most importantly, unlike the vast bulk of these you see for sale, this one is 120V, which means you do not need any sort of power converters to run it on US power.” Link
“Retro vintage analogue synthesiser sound module with owners manual. It powers up ok and my controller can play it, but the tone patches will randomly change (notably to no’s 31 and 81?). Also the individual keys are intermittent, but that could be my controller. A project perhaps for someone with more electronic ability than me? The sounds are warm as analogue sounds should be, and there are banks to store your own sounds, should you manage to get it working!” Link
” Cheetah MS6 Analogue Polyphonic Multitimbral Synthesizer + MAAD OS, box, manual. All 6 voices are sounding and pass the DCO calibration/diagnostics test. New battery was fitted in 2010 so should be good for a number of years.
Has been well looked after as can be seen by the condition.” Link
“Excellent contrition. A real British Classic. Multi-timbral.” Link
An abosulte classic synth, it works perfect so bid with confidence.
Please see all the photos I have taken.
It will be sent recorded, with insurance covering its value.
Will be well wrapped!
Serial Number: J228
Power In: 240V (On board power with plug) ” Link
· The MS6 is six-voice polyphonic AND multi-timbral, so you can have six different sounds on six different MIDI channels! Each voice has 2 oscillators so it can sound very full and lush.
· It can be edited from the front panel and sound patches and multi-timbral voice performance setups are saved flawlessly.
· The MS6 sounds similar to the Oberheim Matrix synths as they share the same voice chips. In other words it sounds excellent: gorgeous strings and pad sounds!
· IMPORTANT: This MS6 is in excellent condition cosmetically, and is in stable working condition except for one issue: all voices are fine except for voice 5: this voice chip probably needs a tune up or replacement. It can sound distorted and sometimes drops out altogether (except on some of the bass patches). The voice chip can be replaced by ordering a new replacement from the Christoper Maad website for $24. (To temporarily get around this voice issue, voice 5 can also be bypassed in the multi-timbral performance settings menu, making the MS6 function as a five-voice synth instead of a six-voice synth.)
· The MS6 has a U.K. power supply (240v) as standard.
· The Cheetah MS6 can also be upgraded with a third party operating system by Christopher Maad, which adds even more features (MIDI CC controls, added waveforms, etc.)! It can be ordered from the website, along with extra voice chips and sounds patches.” Link
“Can’t tell you anything about this. Got it given last year. I think it’s 80′s technology. Your best bet is having a look online to see what you can find out about it. No manuals.” Link
Module is in very good condition for being used, no scratches etc, was in a rack.
I have some code sheets included and also assignment numbers can still be read from the top of the unit.
Please look this up on the web if you need more detail.
Unit in fully working/functional order.” Link
Zum Verkauf steht ein Cheetah MS-6
Der Cheetah MS-6 ist ein 6-stimmiger Racksynth und spielt in der Liga vom Matrix 6 / 1000,
da er ebenfalls die CEM Filterchips besitzt.
Äußerst einzigartig ist die Möglichkeit ihn Multitimbral anzuspielen,
ein absolut seltenes Feature für ein Gerät aus dieser Ära.” Link
“Massive sounding poly synth with a total of 12 oscs… that’s 2 per voice which can also be layered to fatten things up even more. If you want that Oberheim style sound without spending £3000 then this will come close! This totally blows any Juno away with the power and depth of sound. They only have a single osc which is a massive difference
New battery just fitted
MS6 six voice multi-timbral so you can play lots of sounds at once from your sequencer/daw. Lovely lush sounding with great strings, pads and classic Oberheim sounding brass. Even has aftertouch from the keyboard too
Basically the same synth engine as the Oberheim Matrix using exactly the same CEM chips
Has lots of stored patches for you to play with or just make your own. I can supply a print out of the manual or a pdf file
Very nice synth and a great change from the more usual Roland sounds……. Its by far a bigger and better better sounding synth than the usual Roland Juno 106 synths. Now getting very hard to find as people are now hanging onto them
connections for midi in/out/thru and audio out. Power unit built in, voltage selection switch
Tested and working but one voice does require a couple of mins to warm up and settle down then works perfectly… thats vintage analogue for ya!
The MS6 is a full-featured analog synth with 12 oscillators with PWM, noise and sync. There are 6 analog 24dB/oct filters which are warm and resonant! The MS6 has been used by OMD and Rick Wakeman. ” Link
