Pitch to move parameter position?

How do I use pitch information from an audio file to change a position of a parameter on an effect? Like low would have the parameter arrow at the start of an parameter and high at the end, so the effect goes from start to end depending on pitch/melody.

What format is your pitch information?

I’d venture to say Hz!

it sounds like something you could do in TouchDesigner by normalizing the incoming frequency (such as 0=0 Hz and 1=20K Hz or whatever you set your range to be), pairing it with an OSC string and sending it to Resolume.

Doh! I saw “information” and assumed there was some sort of data track involved not just the audio!
