Bachus - I agree there are a few things not entirely implemented in the current Wersi OAX code that would be helpful, especially on the MIDI side of things. The good news is on the Wersi side we can create what they call a "user sound" that will call up any voice in the Ketron from the Wersi. Next step is to save that "user sound" in a "user preset" (again on the Wersi side). Think of that as the same thing a Registration on a Ketron. All the various volume/expression controls work along with sustain pedal. Having said that I'm guessing I'm a very rare owner of both a Wersi and a Ketron and attempting to use the Wersi as a MIDI controller (once in a while!). Most of the time we use a Komplete Kontrol S61 MKII which doesn't make all the great of a controller for the Ketron, but it does make a killer controller if you own Native Instruments VST's or others that conform to the NKS standard.
