For those who are wondering... the "M" series CS synths do NOT sound like the standard CS's like the 10,15,30 etc. The m's sound more like a Moog than any other. Smoother and to me, sits better in a mix. These 20m's are amazing for creating some unique sounds. Basses and leads for sure, but the modulation routing is very deep, Every VCO, the Filter and the EG has it's own modulation type selector and amount. so you can essentially have a Sine wave, a saw wave, a S/H and a Tri wave going at the same time!!!! All clocked to the internal LFO Speed! Everything works, It keeps pitch great. Also has CV I/O!"
