Measure X - control parameter Y - General approach?

Hi guys,

my brain doesn't handle it or lack creativity. I'm wondering about a general approach. DAW is Reaper or Studio One.

I want to generally be able to make a measurement at one point/track. Let's say, the simplest, some current average volume level.

Depending on the current measurement I want to control parameters, at best ANY, whichever I like. Let's say some feedback parameter of some VST plugin.

What is the approach here? Some extra plugin which measures - and permanently spits out control messages? MIDI CC? Aww I did not yet or use Midi cc.

Or is there something I do not see?

Thx for your input

In Renoise I do exactly this (control a VST parameter with some other channel's volume) by using the Signal Follower. I would imagine other DAWs have similar systems.

Reaper has parameter modulation which works with audio input

And you can also do some stuff with it from midi input

An 'envelope follower' is the general term for the 'thing' you want to be using for this kind of technique. There are probably lots out there (I use some Max 4 Live devices in Ableton as find it easier to map what I wanna listen out for and what I want to modulate) but the first (free) one that comes to mind is MCCGenerator:

What HMA said, Reaper has this built in.
