There is the keyboard shortcut "cmd + enter", or this is also under Options | MIDI Patch Maps | Insert current MIDI chord. This shortcut can be used to insert a chord that's played on your MIDI keyboard. There is more info on this feature in Chapter 4, under Chord Entry, page 57 of the manual for Band-in-a-Box Mac 2020. https://www.pgmusic.com/manuals/bbm2020full/chapter4.htm

However, there is not a window/dialog that pops up for chord detection in the Mac version like there is in the Windows version.


Best,
Chantelle
