128 Effects
Chorus, Flanger, and Phaser (Cho/Fln Phaser)
39: St. Random Flanger
(Stereo Random Flanger)
The stereo effect uses a step-shape waveform and random LFO
for modulation, creating a unique flanging effect.
40: St. Env. Flanger
(Stereo Envelope Flanger)
This Flanger uses an envelope generator for modulation. You
will obtain the same pattern of flanging each time you play. You
can also control the Flanger directly using the modulation
source.
c: Sweep Mode
c: Src
This parameter switches the flanger control mode. With “Sweep
Mode” = EG, the flanger will sweep using the envelope genera-
tor. This envelope generator is included in the envelope flanger,
and not related to the Pitch EG, Filter EG, or Amp EG.
The “Src” parameter selects the source that starts the envelope
generator. If you select, for example, Gate, the envelope genera-
tor will start when the note-on message is received.
When “Sweep Mode” = D-mod, the modulation source can con-
trol the flanger directly. Select the modulation source using the
“Src” parameter.
The effect is off when a value for the modulation source specified for
the “Src” parameter is smaller than 64, and the effect is on when the
value is 64 or higher. The Envelope Generator is triggered when the
value changes from 63 or smaller to 64 or higher.
d: EG Attack
d: EG Decay
Attack and Decay speed are the only adjustable parameters on
this EG.
