Thanks for your detailed explanations and screenshots. I think I had a pretty good grasp on the concepts you had provided.

Here’re just a few follow up questions need help.

Copy/Move MIDI Notes
What does it mean by “Move the cursor (in the area where the chords are displayed) to the position that you want to paste to”?
In the piano roll, after select the notes and press Ctrl+C, what should I do then? Can I turn the snap on, move the cursor to snap whatever grid (bar grid, beat grid, 1/16th grid, etc), and then press Ctrl+V?

Import MIDI to middle of the bar
Say, I want the beginning of imported MIDI to be aligned to the middle (beat 3) of bar 10. Can I simply enter 240 ticks in the "Include notes played before" box at the bottom right corner? I assume one bar is divided into 480 ticks.

Completely Disable 2 Bar Count-in
Is there a way I can disable the default 2 bar count-in all places in BiaB (preview, playback, audio export, MIDI import, and everywhere else)? So bar -1 and bar 0 will completely disappear, and I’ll never have to worry about offsetting when drag & drop a MIDI. No more math.

Force Not to Gen/Regen
In the chord sheet, is it possible to have no chord assigned to bar/bars, so later when switch to Audio Edit window, no waveform is generated for that portion. Say, for the first half of the song, I inserted an long audio to bar 1, and I want it to play from bar 1 to bar 32, nothing else is generated or plays. Then start from bar 33, the audio ends and BiaB generated sounds start to play. I know I can use volume automation or bar settings to mute things, but would be better if waveform not generated in the first place. Can I delete the chord on bar 1, so from bar 1 to 32 the chord sheet is blank and not generating?
