Hey, thanks for the additional input.
I went into a guitar store and tried another DMB, same thing happened, as expected.
Also, it definitely happens with +1 octave and above too!
I figured it’d be some sort of latency coming from the units, but still had some desperate hope, I guess. Actually, and unfortunately, putting dry signal in the mix just makes it messier.
Thanks for the input!
I realize it sounds obvious, but I should mention this only happens on the pitch-shifted signals, my bad!
