chorus duplicates the sound running through it and shifts the pitch and timing very slightly, or very dramatically. this can be used to create a wider sound.
rate
rotate the dark gray knob to adjust the rate of the chorus, this is how fast pitch of the sound running through it is modulated.
depth
rotate the mid gray knob to adjust the depth of the effect and thus how much the pitch of the incoming signal is modulated
feedback
rotate the light gray knob to adjust how much the chorus feeds back into itself, this can be used to create a pitch modulated delay at higher feedback amounts.
stereo
rotate the white knob to adjust the stereo width of the chorus, spreading the sound.
delay repeats the incoming signal creating an echo.
size
rotate the dark gray knob to adjust the spacing between repeats. there are 8 options ranging from micro to insane.
amount
rotate the mid gray knob to fine tune the distance between repeats.
fine
rotate the light gray knob to adjust how much the delay feeds back into itself, extending the delay and thus the number of repeats.
dry
rotate the white knob to adjust the amount of the dry signal with respect to the delay. setting dry to 0 will result in only the repeats with none of the initial sound.
phasers comb through your sound with filters, then mix them back with the original audio, cancelling out whatever is out of phase. OP–XY features a 12-pole phaser, that’s 12 notches on the comb.
frequency
rotate the dark gray knob to adjust the center frequency of the phaser. this is the frequency around which the phaser moves.
depth
rotate the mid gray knob to adjust the depth of the phaser, the higher the depth the more it moves.
rate
rotate the light gray knob to adjust the rate of the phaser, turn it up to go faster, or down to slow it right down.
feedback
rotate the white knob to adjust the feedback of the phaser, this changes how much of the signal out of the phaser feeds back into it. turn it up and hear it sing.
