Semi OT side issue warning. Absolutely fascinating. This explains much about why I often fail to understand explanations.

With all due respect Maarten, You _have_ managed to make it look like rather complex math. Either that, or I'm dyslexic. I would explain it thus: each beat lasts 60/bpm seconds, multiply by the number of beats in the bar. That will give you the length in seconds, you an convert that to length in Hz as above if you need to. 4 beats to the bar _is_ the default setting, if you like. but best to check otherwise you may end up with a loop twice or half the length. It's really ok to have odd numbers of beats to the bar if you want, but that's just personal bias. cheers tim hall
