thanks for that

what is the LFO in that diagram

sorry im an idiot…

if someone could correct this patch I made, that’d be great.

i had a quick go at recreating the circuit – for my lfo i used the cycle~ object but you could use any signal generator. I had a go recreating the colour control – i’m not sure how they do it in the pedal but in my patch it switches between using one or all 4 filters.

Have fun with it and improve and post back!

LFO means low-frequency oscillator. Just a waveform (sin, saw, etc) at a really low frequency.
