First of all, the CZ1 IS velocity sensitive, and it is 8 voice poly (16 if you use only one channel, but the sounds are thin then). I'd STRONGLY recommend you allow an extra $75 or so for a cheap effects box of some sort (a used Alesis Nanoverb for example). I have one dedicated between my CZ1 and mixer and it brings the synth to an all new level of usefulness (the on board chorus is so noisy it's almost useless and there're no other effects to speak of). I think perhaps you or the other posters are referring to the CZ101/CZ1000s which ARE 4 voice poly and ARE NOT velocity sensitive. A CZ1 for under $200 is a good deal.
