I LOVE the MIDI editing in BIAB. So easy. In fact, I use BIAB for data entry of MIDI no matter where the song will wind up: DAW, notation program - whatever.
We must be using two different versions of BIAB Matt.

Yesterday I figured out how to do some basic midi note inputting (Notation editing mode).
Maybe someone can tell me how to delete a bunch of selected notes?
I tried hitting 'delete' but nothing happened.
I had to resort to deleting one note at a time, which of course was very tedious.
I just had a chat session with a PGMusic tech guy and he said you do these things in Piano Roll mode!
Well, if you're me or like most folks who don't play the piano but read music, editing in Piano Roll mode is the most unintuitive way to edit music!
