Just recently got a (like new) cs01. Turned it on for the first time and no sound could be heard for over a minute, thought it was broken but no its analog and has to warm up (face palm time).
Anyway, what a great little kb. If you can get one, do it.
Im waiting for the new midi retrofit to come out and i'll be set.

wow very old thread , i forgotten it (2009)...but cool! you got now this synth.
any possibility to hear or post some sounds/patterns of it?
