I don't know if that exists but if it does it would be really useful.
What I am looking for is this...
I would like to change each track's tempo (bpm) with a specific code.
For example, In track one, I'd like to change the tempo to 100bpm but in track two, I'd like to change the tempo to 150 bpm for example. So each track's tempo should play different than the main tempo.
By the way, I am not high right now.
