Regarding compound time signatures like 12/8 ( or 6/8 or 9/8


BiaB already supports 12/8. Including notation, and chord entry (using 3 MicroChords per beat).

For playback, it is treated as 4/4, because that’s how most musicians count it.
Here’s a good video explaining that https://youtu.be/SQbrGlyG-vw or this one https://youtu.be/cItjWpgDTTk


Same idea for 6/8 (which is like 2/4, assuming that the feel is two groups of 3) also supported in notation in BiaB.(with 3 MicroChords per beat)
And 9/8 (counted as 3/4 with 3 groups of triplets). BiaB, with 9/8 notation available; and 3 MicroChords per beat.


Have Fun!
