It's funny, even my old M Audio Venom has 14-bit midi cc-control of some parameters, take a wild guess which... Of course the pitch bend is 14-bit, but then also filter cutoff, voice detune and osc 1 2 & 3 detune. Mostly tuning parameters basically (filter arguably, but even more important anyway because of potential stepping, imo). Makes sense. The rest (afaik) are 7- or 8-bit. I'm still quite surprised SCI hasn't implemented this in their more modern synths (yet). Though I have a Rev2, I really wouldn't have got it if pitch bend was limited to 8-bit, and I was kind of on the fence on it because of filter cutoff being limited to 8.
I would think there are others like me, some perhaps still on the other side of the fence because of said issues. Having such a great filter BUT with such limited midi control over it, in 2018, blows my mind. In reasoning terms at least, I just can't understand WHY NOT?!
