I'm an ex CZ101 user.
Programming is more or less the same, if not better than the original. Ring and Noise modulation is there (on the DCO 2 menu).
There are some things I'm missing:
Solo mode, in which, by playing legato along with the 8 stage envelopes you had a complex evolving sound. That said, changing values doesn't retriger notes (as it was happening on the CZ101) so you can tweek your sound while you play notes. Double mode, in the original you could combine 2 sounds for a 2 note polyphony sound.
Filter with resonance is a great addition and it sounds good.
Chorus is not stereo, I have better options via external effects.
3 voice polyphony is limited. I hope it will increased with a future update as it happened with Pro VS mini.
Maybe is the best sound design tool you can buy, for that price.
