I haven't found much info on this from web searches... maybe I'm using the wrong terminology or something. It seems like a relatively basic thing considering the complexity of modern DAWs, and considering analog synths have done similar things with control voltages for a long time.
Essentially I just want to control a parameter using the amplitude of another track. So, for example imagine a kick drum pulsing and the synth's LFO rate being influenced by that pulse (change in amplitude).
I believe if I were using Reason this would be done using audio to CV on a Combinator. I can't figure out what the equivalent in Live would be.
Thanks in advance if you can point me in the right direction.
