Hi everyone! I’m trying to do the simplest thing ever: apply an envelope to a filter ( SynthDef.new(\sine2, { |freq=40, atk=0.03, sus=0.03, rel=9, pan=0, gain=1, trig=0, amp=0.08, out=0| var sig, env, filter; sig = VarSaw.ar(freq, width: 0.85); sig = tanh(Line.ar(0.001, gain) * sig); sig = si…

[image] InsulaDulcamara: filter = BLowPass.ar(sig, EnvGen.kr(Env([20, 10000, 20], [4,4]), trig)); Out.ar(out, sig); You aren’t actually outputting the filtered signal. Swap Out.ar(out, sig) to be Out.ar(out, filter)

Modulate an LPF Freq cutoff using an envelope or LFO Questions

You can definitely use the same envelope for controlling different things in the same Synth. The adsr envelope will range between 0 and 1, which is good for amplitude, but not specifically for controlling the cutoff of a filter. You’ll need to scale the value of the envelope when setting it to control the LPF’s cutoff. There are several ways to do this: You can either straight up multiply and/or add values to it to get it into the range you’re after. If you want to control from 200 Hz to 700 …
