Voice Parameters

1-2-9 Amplitude EG (Envelope Generator)

This lets you control the transition in Amplitude from the moment the sound starts until the moment the sound stops. You can create a custom Amplitude EG by setting parameters as illustrated below. When you press a key on the keyboard, the volume will change according to these EG settings.

Determines how quickly the sound reaches its maximum level after the key is pressed.

Determines how fast the envelope falls from the Attack Level to the

Decay 1 Level.

Determines how fast the envelope falls from the Decay 1 Level to the

Decay 2 Level (sustain level).

Determines how quickly the sound decays to silence after the key is released.

Determines the initial level at the moment the key is pressed.

Determines the maximum level which the envelope reaches after a key is pressed.

Determines the level which the envelope reaches from the Attack Level after the Decay 1 Time elapses.

Determines the level which will be maintained while a note is held.

Voice Parameters

Half Damper Switch Determines if the Half Damper is switched on.

When the Half Damper Switch is set to On, holding down the FC3 Foot

Controller produces a "half-pedal" effect just as on a real acoustic piano.

Half Damper Time Determines how quickly the sound decays to silence after the key is released while holding down the Foot Controller FC3 with the Half Damper

Switch set to On.

After releasing the key, you can control the decay time of the sound via the

Foot Controller position, with the Half Damper Time of the AEG being the maximum decay value and the Release Time of the AEG being the minimum decay value.

When you release the pedal, the decay time after the key is released is equivalent to the AEG Release Time. You can create a piano-like effect by setting the Release Time to a small value and setting the Half Damper

Time to a large value.

EG Time Velocity

Sensitivity

Determines how the AEG transition time (speed) responds to Velocity, or the strength with which the key is pressed.

„ Positive values: High Velocities result in a fast AEG transition speed

while low Velocities result in a slow speed, as shown in Figure 37 and

Figure 38.

„ Negative values: High Velocities result in a slow AEG transition speed while low Velocities result in a fast speed.

„ 0: The amplitude transition speed does not change, regardless of the

Velocity.

Sensitivity

Figure 38: Positive Sensitivity: Playing softly, slow speed

Determines the part of the Amplitude EG that is affected by EG Time

Velocity Sensitivity.

Determines the degree to which the notes (specifically, their position or

Octave Range) affect the Amplitude EG times of the selected Element.

„ Positive values: High notes result in a fast Amplitude EG transition speed while low notes result in a slow speed.

„ Negative values: High notes result in a slow Amplitude EG transition speed while low notes result in a fast speed.

„ 0: The Amplitude EG transition speed does not change, regardless of the played note.
