Audio to light controller

Hello, I am looking for a way to take an audio input (in my case from a mixer) filter by frequency (probably kick drum) then send a midi note to light controller (QLC+).

The specific use case is to take an audio source input and output a short midi note when it detects the kick drum beat. Has anyone already done something like this? I’m an app developer proficient in many languages including python. I could probably write it from scratch but I’m sure someone has already done something similar.

Any guidance is appreciated!

Hey, I’ve found a similar discussion here which as expected involved Pure Data. :slight_smile: There might be some LV2 or similar plugins out there that can trigger MIDI events based on audio fed into it, or you could get Pure Data to do something like that, or a combination of plugins and PD.
