Thanks very much, Noel. That works!
On your file I changed the tempo to 60, and it goes the same speed as my 3/4 version set to 120 tempo, which makes sense, I guess.

But I have to say I don't really understand what "swing" time is Is the only difference between swing and even the resolution of a quarter note?

I wonder if BiaB will ever have get built in 6/8 time. Maybe 6/8 time isn't very popular.
