From just a quick test, I wasn’t able to reproduce this. Are you able to save a Scene that has this problem and upload it here?

You could put them in a zip file, as long as it is under 5MB, or use one of the many file sharing services out there.

I tested you Scene now and I’m not sure I’m able to reproduce (all of) this. What I do is:

  • Hold a note on synth 1 (blue, PHZ).
  • Press Shift Mixer to get to the MOD fx screen.
  • Twist the Filter Freq knob back and forth.

With this, I only get a little bit of artifact when it goes from Off into the active range and vice versa. But I don’t get anything while sweeping around in the active range.

Am I doing things right in order to try and trigger the problem you describe?

The single pop I’m able to get is probably enough for a bug. It just sounds like you are experiencing something worse and I want to make sure we’ve got it all covered.

That is about the process I went through but mine definitely was more severe than a couple pops, mine was more akin to constant vinyl and happened at all times the filter was on even if I wasn’t moving it around

Are you able to provide at video or at least audio recording of this?

Hi all @here , I also cannot reproduce this issue to get “severe” audio issues without moving the Filter Freq. Subtle audio clicks can happen in following cases:

  • when switching Filter Freq = On/Off
  • when crossing Mod Freq 0 point (switches type of modulation)
  • when using Time Shift (similar like changing Time Delay on a Filter)
  • when switching Models

In these cases clicks are expected and will happen “by design”. Basically, when having a “hard” switch… with higher Feedback clicks can repeat a few times, but not stay permanent. Please provide a video/audio to better understand the nature of the issue reported. Thanks for your support!
