This shows how to playback audio or midi track from the plugin either synced or not.
It would be good to have a way of playing back more than one midi track at a time by ctrl click the track to select more than one or have a solo button or check after the name on the track button.
Track 1 is the Biab VSTi plugin sending channel 2 midi to track 2 Bass using Sforzando
Track 1 is also sending channel 3 midi to track 3 EZKeys
