I start a new project, add 1 virtual synth (Rapture Session).... works fine = outputs sounds.
I then import a midi file (multiple tracks) and assign these to Cake walk TTS 1
I copy the contents of 1 track from the TTS 1 set and paste into the Rapture Session track
Rapture Session refuses to play a note. Even bringing up the synth itself and playing via its keyboard produces no sound
