This perky little VCA/Envelope combo has found itself to be very useful in my rack. It’s a VCA with a Decay envelope built in that you can also feed out to a filtercutoff which saves you a bunch of modules. It has some nice CV control and does a great job of being fabulous without annoying anyone or getting in the way.
