Sorry about that! I never know if it’s better to leave the audio alone (and give a more realistic representation of what it sounds like, and how the controls react) or edit stuff like that so the levels are more consistent, and worry that it might misrepresent what’s being shown.

That’s just the sound of the synth. The microbrute has a control called “brute factor” which takes a copy of the output and reroutes it back into the synth. Which can add distortion.
