David, Dan got me thinking about the MIDI only option so I did some experimentation. Would you verify this method for me.

1-Load the VSTi with a MIDI song
2-Under generate/custom click on all pages (MIDI only)

I am using BiaB 2021 and when I do the above the generation is almost simultaneously. Also only the tracks' mid files are saved in C:/bb/bbplugin. No audio tracks were generated. This is a game changer for me.

The fitness trainer asked me, "What kind of a squat are you accustomed to doing?" I said, "Diddly."
