22: 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 modula- tion source.

e: Swp Mode, e: Src

This parameter switches the flanger control mode. With “Swp Mode” = EG, the flanger will sweep using the envelope generator. 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 generator will start when the note-on message is received.

When “Swp Mode” = Dmod, the modulation source can control 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.

f: EG Attack, g: EG Decay

Attack and Decay speed are the only adjustable parameters on this EG.

23: St.Phaser

(Stereo Phaser)

This effect creates a swell by shifting the phase. It is very effective on electric piano sounds. You can add spread to the sound by offsetting the phase of the left and right LFOs from each other.

g: Resonance, i: W/D

The peak shape of the positive and negative Feedback value is dif- ferent. The harmonics will be emphasized when the effect sound is mixed with the dry sound, if you set a positive value for both “Resonance” and “W/D”, and if you set a negative value for both “Resonance” and “W/D”.

h: High Damp

This parameter sets the amount of damping of the resonance in the high range. Increasing the value will cut high-range harmon- ics.
