Chorus; Flanger; Phaser; Tremolo - DigiTech BP90 Owner's Manual

Chorus

A Chorus adds a short delay to your signal. The delayed signal is modulated in and out of tune
and then mixed back with the original signal to create a thicker sound. The BP90 Chorus effect is
based on the Dual Chorus. Chorus settings are C1-C9.

Flanger

A Flanger uses the same principle as a Chorus but uses a shorter delay time and adds regeneration
(or repeats) to the modulating delay. This results in an exaggerated up and down sweeping motion
to the effect. Settings are F1-F9.

Phaser

A phaser splits the incoming signal, and then changes the phasing of the signal. This signal is then
taken in and out of phase and mixed back in with the original signal. As the phasing changes, differ-
ent frequencies get canceled resulting in a warm sort of twisting sound. Settings are P1-P9.

Tremolo

A Tremolo effect modulates the volume of the signal at an even rate. Settings are t1-t9.

Panner

A Panner modulates the sound from left to right at an even rate. Settings are n1-n9.

Vibrato

A Vibrato effect modulates the pitch of the incoming signal at an even rate. Settings are b1-b9.
