Hi... as I've just started using my P12 in multi mode I've ran into something I do not like. I'm not sure if this is a bug, or if I have made some wrong settings, but when in multi mode, and controlling the two parts from my sequencer, the P12 seems to take MIDI volume (CC7) messages, and apply them to both channels at the same time.
If I change the volume on say; channel 1 (A), then the volume of part B also changes in volume.
Is this a bug? ... it makes it a bit irritating when trying to set levels for the two channels from your sequencer.
