dsprojectI got it working by using the APro Editor. I just assigned the Hold (P1) as a channel message - Control Change - Midi Ch.1 - CC64 - Min 0 - Max 127 - Port 1 - Unlatch. I used Control map 19, a sustain pedal in "closed mode" and I have ACT on. If you have a sustain pedal in "open mode", I guess you have to switch the min and max values. And it worked :)
