Try adjusting your attack (soft touch, hard touch, etc.) as well as plucking/picking position. Muting technique is also essential as any ringing/extra notes will confuse the circuit and make glitches. Start with octave 2 rolled back all the way and a 50/50 mix of wet and dry. Try the above, then slowly bring in ocave one. Add ocatve 2 to taste. Run it full wet just to hear what's happening to the effected signal. Try playing staccato first. The OC-2 tracks better with short notes, then begins to fart out on the sustain as the signal decreases.
