Modulating multiple filter cutoffs in cascade~
My goal here is to use LFOs to modulate multiple cutoffs in cascade~. In this patch I have a simple square wave going into cascade~ with filtergraph~ to edit it. LFOs are there to manipulate the cutoff frequencies. I found that packing multiple cutoff frequencies into the cutoff inlet of filtergraph~ was ineffective. My next thought was to unpack coefficients from filtergraph~, modulating them, and than packing them into cascade~.
The question is, how can I manipulate these coefficients so that only the cutoff is affected? It appears much less straightforward than changing a cutoff.
Pardon the messy patch.
I tried something like this recently, i used individual filter graphs and cascades to modulate each band instead of trying to do it all in one which was simpler for my purpose. the packed message threw me off
