I was inspired to create this by the recent release of Bram Bos’s Skulptur effect. I haven’t used Skulptur yet and I’m not even 100% sure what it does, to be honest—but this is probably a distant cousin. More subtle and less tactile, that’s for sure. But also free! Have fun!

FILTERGATE is 10 bandpass filters that each have a LPF that is controlled by one of two LFOs. Each LPF is also hooked up to a delay, which can be controlled by the sliders. So by moving the sliders you can spectrally shift the gate sound. I dunno how else to explain it. Just try it.

0.2: Changed methods, fixed a couple bugs.
0.3: A few little refinements. It’s probably finished.
