I connected a volume pedal (EXP ped.) to the Volume CV jack.
It works as I can control the volume with my foot, however I hear a strong scratching noise in the audio signal of the Minitaur (REV 2) when moving my foot.
I tried 3 different pedals, all with the same result. Those pedals are working ok with the keyboarder.
I’d give Moog a call on this one, since you tried 3 different pedals with the exact same result each time. I’m guessing it must have something to do with your Volume CV or Volume CV Jack.
