Roland CMU-810 CompuSynth

Roland CMU-810 Image

The CMU-810 is one of Roland's first Expander type modules. It basically has the same guts and sounds as the MC-202. The overall layout mirrors the MC-202 and SH-101 synthesizers very closely. Along the bottom row are sliders and switches for the Oscillators, 24dB VCF analog filter and ADSR VCA envelope sections. The upper row contains the LFO controls and a simple Mixer section. External audio can also be routed in (but not through the filter). Up to two external sources can be added and their levels mixed in.

This is a rare but capable analog mono-synth. It can generate true MC-202/SH-101 bass sounds which have become very popular in electronic music. The CMU-810's obscurity does not come with a heavy price tag either. In fact, they often make a cheaper alternative to the more common Roland bass/lead-synths. But you'll need some sort of CV/Gate to play any sounds. It has been used by Astral Projection.

This beast is NOT a SH101. Sounds WAY bigger; I can even say it simply sounds HUGE, more in a SH2/system 700 fashion. Even bigger I would say. If you are lucky enough to see one for sale, don't miss it, it 's really worth the price (I paid mine $900).

Great little über-rare box, I also have an SH 101 and garantee it sounds fatter, the difference is very audible. As the first comment says, it has deeper bass.
About the price, it's not as cheap as the review says! I also agree with the first comment: the few ones I watched on ebay were sold in the 1000 usd range. Never saw one for 500...

Concerning the price tag, the last CMU-810 on Ebay was sold for less than 500 usd...
