VCA Block

The VCA parameters give you control the overall volume or level of the AN voice.

• VELOCITY (VCA Velocity Sensitivity)

Range: -64 ... +63

This determines how the VCA (voice level) responds to key velocity. For positive values,

playing the keys with greater strength results in higher volume. For negative values, the

relationship is inverse: a softer key touch results in a higher volume. A setting of “0”

results in no change in volume by playing strength.

To set this, click the VELOCITY button and highlight the desired value in the pop-up

chart. When a value other than “0” is set, the VELOCITY lamp lights.

• VOLUME

Range: 0 ... 127

The VOLUME setting determines the overall output level from the VCA before the signal

passes to the Effect block.

AEG (Amplitude Envelope Generator) Parameters

The AEG parameters allow you to shape the sound of the AN voice. In other words, it

lets you set how the level of the voice changes over time.

• AEG ATTACK (Amplitude EG Attack Time)

Range: 0 ... 127

This determines the Attack Time of the AEG, or how long it takes for the sound to reach

full volume when a note is played. Higher values produce a longer Attack time. (See

illustration below.)

• AEG DECAY (Amplitude EG Decay Time)

Range: 0 ... 127

This determines the Decay Time of the EG, or how rapidly the sound dies out (or goes

down to the Sustain Level) as a note is held. Higher values produce a longer Decay time.

(See illustration below.)

• AEG SUSTAIN (Amplitude EG Sustain Level)

Range: 0 ... 127

This determines the level of sustain of the AEG, which is the level at which the volume

will be maintained as long as the key is held. Higher values increase the Sustain level.

(See illustration below.)
