Cheetah MS800 Synth Module
Digital Wave synthesizer


A buget module from the nineties from English society Cheetah, most known for their rack MS-6 a kind of Oberheim Matrix 1000 clone.

info MODULE half rack module.
The main panel is pretty poor featuring a cryptic segment display and 10 buttons for whole edit.

Rear panel terminal connectors:
- main signal out (mono + stereo)
- Midi interface.

ac Power supply non-standard external PSU: be sure to get the right one.



edit VOICE the unit manages up to 15 voices but it is possible to increase the polyphony chaining various Ms800 modules.

MS-800 Structure a basic sound patch is composed by up to 14 PCM* voice in layer or TONES (each PCM uses 1 voice from the polyphony) and each tone has some editable parameters:
- analog out assign (L/R 1/2)
- pitch detune amount
- pitch transpose (+/49 cents)
- velocity curve response (0-4 presets)
- volume gain (0-99 scaled).

* only slots 51-54 can have 14 tones while 61-70 up to 5 tones finally 81-99 only 2... complicated uh?


WAVEFORMS internal ROM features 21 companded waveforms at 8 bits resolution - pretty dirty and aliased.

Most of wavetable contains basic waves (e.g. sinewave, triangle) noises and harmonics. FULL WAVEFORMS LIST


ENVELOPE no EG generator but a simple attenuation parameter: a kind of attack and a release.

special wave cycling mode for textured sequences a bit like Korg Wavestation or Commodore 64 wavetable. The MS-800 wavesequence creates some harsh digital sequences but it badly lacks a filter structure.

Here's roughly the typical wavesquence edit structure, but be aware that the interface offers quite no clue about your programming steps, so get paper and pencil and get note -- old fashioned way.

STEP 1- waveform numer
STEP 2- volume step amount
STEP 3- step time duration (m.seconds)
STEP 4- crossfade time (smoothes wavefrom transition for clicks, like Wavestation)
STEP 5- go to [next wave] xor [LOOP] or [END].

Some parameters are not "yet" implemented (for future expansion - lol):

MIDI unit is multitimbral and manages some basic Midi parameters including: velocity, pitch bend, program change and exclusive systems.
Sadly no computer editors.

functions 2

- 50 ROM patches
- 49 RAM patches
- 50 ROM tones
- 50 RAM tones.
TECH: Sounds can be saved only by exclusives system using internal MIDI sysex DUMP utility.


MS800 ... another APHEX TWIN JOKE? in 2016, the famous English musician RICHARD D JAMES released the CHEETAH EP with a notable reference to this cheap module. Sounds more like a joke like he previously did for the 2014 album SYRO - also claiming to make use the expander ORLA DS24/12 which is another unspiring and hard to program module, mostly (and still) used as a doorstop.

"Thank you for choosing the Cheetah MS800 digital wave synthesizer module. The Ms800 uses digital sound generation techniques combined with wave sequencing technology to bring you sound with a movement and depth, rarely found in synthesizers history" Manual (lol).

Maybe now collectors will rush to acquire this module: willing or not the MS800 is now a cult machine... but not for the sound.

REVIEW : "Like Evolution EVS-1, the MS800 makes low fidelity digital industrial noises. No editor, no libraries, nothing... for early digital geeks masochists or Aphex twin fans."
