I have connected a Roland 700NX to my iPad. When I make a recording with Cubasis using the sustain pedal, it sometimes does not record key-off messages and keys are not switched off. After playback I have to exit Cubasis to switch them off. Also Cubasis does not record the pitch wheel control data, although in real time, the effect of the pitch wheel is heard.
This is quite a disappointment and I hope an update will fix this soon.
