VCA's & Envelope Following - Exploring Volume Modulation & Envelope Extraction

Welcome to the 4th part of episode 1!
In this part, we take a look at what a VCA & envelope follower is and how they work - where we can modulate amplitude, modulate modulation, use a drum loop to create a locked in rhythm bass sound or even auto-wah effects.
And of course, as always - we take a look at how each circuit works behind the panel itself.
Enjoy!

Beautyful vid 😁

I recently made up an envelope follower and I gave it an amplifying attenuverter on the output, so it can do between +-2x the actual envelope voltages. It's quite useful that way. Actually I made 2 of them on one pcb with a gate extractor too, which gives a gate whenever the follower goes up, so you can then trigger something else based on original the envelope...

That's such a neat idea! I should have added more features now! Hahaha

Got to get yourself some knobs for those pots.

[@sebbothebushnerd]

I really do! Hahaha.
The ones on there are some I have from my late grandfather; but tackling the rest of the pots is a job for another time!
