If you import an SGU with a rendered M4A to the app, it does not require internet access to play the M4A audio instead of MIDI.

The apps have some limitations (for now):

MIDI Styles: Changing most song variables (key, chords, part markers) generally requires a local, offline regeneration. Tempo changes and instrument mute, volume, or patch change will apply in real time.

Real Styles (And any song with rendered M4A audio): Changing song variables, tempo, and track volumes need a regeneration on the server.

Realtime tempo control is an anticipated addition to both apps in 2026.
Great! Thanks again. I'm going to be upgrading to BIAB 2026 tomorrow, and I'm going to be spending some serious time with the app to get familiar with it. I'll be looking forward to trying out the various changes you'll be making with it as it grows.

Thanks very much again for your efforts, Merry Christmas and Happy Holidays to you and yours.
