Well...

This is beyond frustrating.

All I can figure out how to do is import my MusicXML files into BiaB and render an MP3 backing track with NO metronome. When I enable the metronome, I can't figure out how to change the sound of it.

Figuring out how to create a click track IN BiaB is beyond my comprehension with what is available in searches on the Internet or the manual.

Do the steps involved really have to be this elusive?
