Hi all, I'm getting a low pulsing "beating" type of sound in the synth included here. I can't seem to get rid of it. I'm quite sure it's coming from the PWM LFO, since it can be sped up and slowed down. You can hear an audio demo of the synth, error included, here: Malter Any suggestions much appreciated! (I'm running Csound 6.08, linux.)

Unless you can give us a simple CSD demonstrating the issue, we can’t do much.
It may be just how it is. Virtual Analogue oscillators such as vco2 may have limitations or issues.

Can you give the values of the various sliders/buttons/whatever? I agree
with Victor there is not much with wich to get to grips.
6.09 is raer old -- December 2016 I think

Hi everyone, I included the csd file as an attachment in the first email. The first email link also links to the csd file itself. Hence the second message with new audio link.

could you provide an example with the parameters that reproduce the issue, without a gui?

I tried to run your csd but could not get any sounds/ Mind you I do not
have jack and am MIMI challenged
That is why I asked or values.

I *think* the problem is with LFO3. Here is the full code:
