Beads Manual Gain Adjustment

Following the manual gain adjustment procedure as described in the manual, I am having no luck with it. “Mutable Instruments Beads overview and patch book” by Analog Sounds has a good example at 5:32 on youtube. When I do this there is no change in volume, and no change on a scope.
Could I be doing something incorrectly, or need to do some sort of reset on my unit?
Thank you!

No.

Probably.

there is no change in volume

Are you sure you’re not listening to a delayed, or another kind of wet signal here? In that case, adjusting the gain won’t have any immediate impact.

I unpatched completely to give it another try with just a sawtooth wave. And yes, I was doing something incorrectly. I interpreted the manual as to hold the quality selector button for one second before turning the feedback knob, as opposed to simply pressing the button and turning immediately. Thank you for your quick ( and direct) response!
