currently, on the pro 2 usin 1.1.15, several knobs don'tsnd midi when midi out is set to CC. ENV 2 Amount, Filter 2 Cutoff, and filter routings are a couple that come to mind. they send NRPNs fine.
the issue is when set to CC and local is OFF, those knobs are dead. using NRNs in ableton is really cumbersome, so CCs are preferable, but the knobs that dont work are really annoying.
thanks, d
