I develop modules myself, poetaster's tonetoys, so I always need a rack on hand for development purposes. But one with a keyboard, arp., midi in, etc, etc is more than I could hope for. I play it every day.
The keys/aftertouch/velocity are responsive and mapping ratios seamless. The zone setup with splitting is just great. The auto chord function works well.
It's a really great bargain and thank you cre8audio!
