Well, that's suddenly obvious haha. Easy to overlook in a different context.

When I was new to all of this, and asked the community "hey, how do I make an OTA work like a voltage controlled resistor" the response was "well you can't, figure out how to need a VCA instead." wild. It works really well in the this context.
