I have a variety of pedals and midi controllers, and while I can map cc#64 and get the sustain pedal to switch on and off fine using controllers, I don't know which midi code to use for the 'soft' pedal (ie the the 'una corda' pedal on the left out of the three in the pedal graphic beside the on screen keyboard).

I can click on the screen pedal to engage it while playing of course, but I'd rather keep both hands playing piano.

Can someone assist?
