Question How to adjust a pitch shifter Answer To avoid "glitch" and adjust correctly the pitch shifter effect, be careful to the Input level, set it to optimum level. At its maximum, it must be close to 0 and sometimes, the red leds can light but not often otherwise there is a risk of input distortion and overload the Analog/Digital converter. Be careful to the delay function of the Pitch Shifter. If you want a prompt response of the pitch, set the delay to 0ms. The feedback as well. Be sure to play with a tuned instrument and be careful to set the two Pitch voice parameters to a "in tune" sound. Finally, avoid to play unorthodox chords. Play simple 2 sounds intervals as fourth or fifth. .
