Could someone help me with the Piano Roll in BiaB 2022 Windows? The videos seem to jump into the process where the basic setup is already properly established. I'm not sure my basic setup is correct.

I want to add individual electric piano notes into a new song I'm creating so
1. I right-clicked Utility Track#1
2. Selected MIDI Super Track
3. Chose a piano from the list (did not see any electric pianos)
4. Selected the Piano Roll window, I think I know the basics of how to navigate in this window.

I immediately observed that there were MIDI notes thru-out the song. This surprised me as I thought I'd be starting fresh and entering my own notes. It must have picked up the notes from the chords I had entered in a few bars. When I tried to zoom out so I could select and delete these notes, BiaB crashed; some kind of "Exception Error".

Can someone point out what, if anything I am doing wrong?
And is there a video or document that explains the entire workflow of using the Piano Roll that doesn't assume that the setup and any required preferences have be specified properly?

Thanks for any help.

For me there’s no better place in the band than to have one leg in the harmony world and the other in the percussive. Thank you Paul Tutmarc and Leo Fender.
