Phaser
This effect creates modulation by adding a phase-shifted sound.
Parameter Value
DEPTH 0‒100
RATE 0‒100 (when the SYNC parameter is
OFF)
4.000‒0.016 (bars; when the SYNC
parameter is ON)
MANUAL 0‒100
RESONANCE 0‒100
BALANCE 100-0‒0-100 (%)
SYNC OFF, ON
Explanation
Sets the depth of the effect sound.
Sets the cycle (period) of the effect sound.
Sets the frequency range in which the effect is applied.
Larger values reduce the phasing effect in the low end.
Adjusts the filterʼs resonance level.
Increasing the value further emphasizes the effect, for a
more unusual sound.
Adjusts the volume balance between dry (the original
sound) and effect sound.
When this is ON, the effect sound synchronizes with the
tempo.
