Folks,

I've been having a look a the possibility of adding midi controller 
functionality to the P3 knobs in play mode.
I've got a test build running which transmits a volume cc message on 
each track's midi channel when the lower knob is adjusted.
Potentially this could become configurable, so that you can choose 
any controller number and channel to be sent for each of the knobs.
But saving that configuration would eat into the remaining RAM 
space, and may prevent 'per bank midi channels' being possible.
So, if it was a straight choice between these two features, which 
would you prefer ?

Cheers,
