Follower

Tracks the loudness of a sound and outputs it as CV

Open in the synth with a demo patch Open Modular

What it does

Follower (an envelope follower) measures how loud the signal at its input is and outputs that loudness as a smooth CV from 0 to 1. Speed is how quickly it keeps up with changes: 2–4 Hz gives a slow wave, 30 Hz catches every hit. Gain boosts the result so that a quiet microphone still drives the modulation all the way. You plug a Follower in wherever an ADSR or LFO would go, except that now the sound itself, yours or another module's, drives the modulation.

Try this

Send microphone audio to Follower so Filter responds to the volume of your voice.

out: Loudness CV (0…1)

Parameters

Speed · Gain

Try this

Voice → Follower → Filter Cutoff of a second voice: the louder one plays, the brighter the other sounds.
Audio In → Follower → VCA Gain with Noise on the VCA input: a hiss that breathes with your voice.
Follower on the Sampler → Attenuverter (Scale −1, Offset 1) → VCA Gain on a drone: the drone ducks on every sample hit.
