Hello - first post here, fairly new PD user , working on a custom patch for the Organelle, a hardware synthesizer that runs PD inside.
Anyway, I have everything working except an LFO to sweep the moog~ filter object's cutoff. I have researched PD tutorials showing how to sweep a vcf~ object and this works fine, but it takes a number for the cutoff inlet while moog~ takes a signal. I've tried a few things converting and such but nothing that has sounded right. I know I need to get the numbers (with modulation from LFO) converted to signal before it hits the moog~ cutoff inlet. This is hard to test because its a Linux object, I'm on PC, so I can't hear any output until I try the patch on the Organelle itself.
As shown, the LFO is obviously disconnected....I need to get that modulation 'added' to the cutoff freq before it hits the signal, but also not be out of range , if that makes sense....for example, I thnk the vcf~ filter has a range of 10k for its cutoff input, but moog~ is like 2100 or so. When I had this partially working, high settings of the LFODepth were causing gltiches/noise/silence.
Here is a link to what I'm basing this on (see bottom example)
