Paul,
You may have made a mistake in the DAW when you set the time signature. This is a common mistake.m
6/8 with triplet feel has three 8th notes per beat. So the DAW (e.g. Reaper) typically gives you two options. To either:
For a triplet feel 6/8 song ….
(Right!) - set 6/8 as a compound time signature with THREE 8th notes per beat, and you tap your foot every three 8th notes. .
Or
(Wrong!) - set 6/8 as TWO 8th notes per beat and you tap your foot every two 8th notes
Here’s an example of a user post that has this problem. Note this doesn’t involve biab, it just within his DAW. And as a result of this mistake, he has two tempos for the same song. Since it is a triplet song, there is only one tempo, which is 53, and so the DAW considering it to be a tempo of 80 is simply wrong, and fixed by resetting the time signature to triplet feel (compound) 6/8.
‘I have a midi track in my DAW that is in 6/8 time. Tempo is set to quarter note = 80; i.e. dotted quarter note = 53”
