I've gotten lost on the 400+ page manual and still havent found what Im looking for. I have all my drums/percussion in Native Instruments Kore Player. I have no problem getting the external synth to be recorded in Reaper using ReaRoute... but for percussion, I really like to use the piano roll. How I can create a track in Reaper..create a piano roll.. have the output of the piano roll be the input (essentially the midi controller) to the Kore Player and then the output of the Kore player go back into Reaper on another track that records it? RECAP - Create piano roll in reaper that outputs to Kore 2 player which plays the drums, and the Kore 2 output then feeds back into Reaper as a .WAV file Thanks Mike
