I haven’t tried this feature of BIAB yet but I have a wild guess about the sync issue. Do your digital audio devices have a word clock connection? What does your audio interface and MIDI synth (if you have an external one) sync to? Is it set to Internal? What model is your audio interface? Is everything set to 44.1?
