I use PTPA 2014.
I would like :
1/ to choose synth sound for each track Inside PTPA ( not having to select them in the hardware synth). In cubase or sonar this is possible by loading instrument definition file ( for ex Xthe P30.ins) Inside the DAW, so that the DAW has the complete list of sounds in memory.
2/ to playback a PTPA midi project using the external synth.
Very basic old fashion PC>midi>synth configuration.
