"Fully refurbished and upgraded with the latest Maad version 1.3/9.0. The battery has been replaced and moved to a safer location to avoid future leakage. Some rack rash (see images) but nothing too severe.

The new MS6 firmware is version 1.3, based on the V9.0 Cheetah ROM, has the following extra features:

MIDI bank select (CC #0), globally and per-part.
Program change per-part.
Remote control of all tone edit parameters using CC messages, both in tone and performance mode.
No more partial drop-outs at bottom C (130.8Hz).
Three more DCO shape settings, both for DCO A and B: off, pulse + triangle and pulse + sawtooth. The new pulse shapes can use PWM as well.
Extended SysEx support: single patch and edit buffer dumps + requests, full dump and status requests.
Mono mode, per-part, with a choice of always retriggering the envelopes or to not retrigger when playing legato (i.e. pressing a new key before releasing the current one).
Portamento, per-part, constant-time (0.015 - 18.3 s) or constant-rate (400 - 0.44 semitones/s). Full-time or fingered (i.e., only in mono mode when playing legato).
Support for bank 7 tones in performances."

"The Cheetah MS6 is six-voice polyphonic analog synthesizer in a 1u 19” rack. It was launched in 1988 by Welsh company Cheetah who blazed a brief but glorious trail through the world of music tech in the mid to late 80s before imploding in 1993. The MS6 is based around a fairly conventional two oscillator > low pass filter > dual ADSR envelope architecture implemented on six Curtis CEM3396 chips, one per voice, which were also used in the Oberheim Matrix 6, 6R and 1000.

The MS6 is often compared to the Matrix 1000 because of its similar form factor and circuitry. I can’t comment on how valid that is sonically because I’ve never used a Matrix 1000, but it should be noted that, unlike the Matrix 1000, sounds on the MS6 can be created and edited from the front panel without an external programmer. Although you may wish to add one, for reasons I’ll go into further down.

Cheetah MS6 Vintage 80s Analog 6 Voice Multitimbral Poly Synth

Pic of the inside below.

"Vintage 80s analogue polysynth, handbuilt in Cardiff!

Six dual oscillator voices from Curtis CEM chips.

Two oscillators per voice, 24dB filter, 2x ADSRs, LFO, PWM, Sync, 6-voice Poly, Velocity sensitive, up to 6-part multitimbral.. pretty comprehensive in a 1 unit rack and sounds good too!

Editing is straightforward from the front panel, though you won't be reading them from the top surface once it's racked! I'm sure there's editing software too, or an external box such as the Kiwi controller (which has an MS6 template) would make this a dream to use. Latest v.9.0 Cheetah OS too.

Very nice condition for an MS6 and fully working. Only noticeable marks are around the rack ears, and you don't see those once racked up. Very clean inside too. I replaced the battery last year and it still has the factory presets in it, have just used a couple of the string/ synth pads really. Have tested it edits and saves new sounds, however. You have 5 banks of ROM presets and another 2 for user patches."
