Hiya! Given the great variety and experimental flavor of many of wren's modules, I was surprised to see it is missing a classic synthesis staple - the LPG, or low-pass-gate. Traditionally this is achieved in analog using a vactrol, but it can be emulated digitally as well (as in the eurorack mutable instruments Plaits oscillator, among others).

Essentially, a low pass gate is a low pass filter combined with a VCA - as the signal gets quieter, it becomes filtered, similar to how many acoustic sounds work. While it is possible to create a sort of Low-pass-gate by sending the same modulation to a filter and VCA in wren, it would be handy if there was an all-in-one vactrol module, perhaps with tweakable response, and a "pluck" input modelling the characteristic slewed response vactrols have.

Just thought I'd put this request out there, nothing urgent of course Smile Thanks for the amazing work!
