Since I cannot find a way to assign a soundfont to a track, I have tried assigning a VSTi soundfont player to different tracks and loading the soundfont into the player.

But I haven't found a way to use a drumset from bank 128 on one track and an acoustic bass from bank 0 on another track. One of the tracks always falls silent.

Or is there a better way to use soundfonts with PTPA?
