I have a brain cracking equation I can't workout, but I'm sure someone
I want to work out a formula for scaling bpm to milliseconds.
example: 30 bpm = 2000 milliseconds (argument in metro)
60 bpm = 1000
120 bpm = 500
240 bpm = 250
I believe this could placed in expr but I have no knowledge of that
kind of language. Any thoughts?
