Sustain Pedal (On or Off)

This determines whether or not the Sustain Pedal will have an effect on the envelope. When turned on, holding down the Sustain Pedal while playing short notes is virtually the equivalent to holding down those notes on the keyboard with some subtle but important differences. If the Delay and Attack are set to 0 and either the Decay is 0 or the Sustain is 99, the envelope will immediately jump to the release stage (if not already there) when the note is released and the sustain pedal is held down. If a long attack is set, and the envelope does not reach the end of the attack segment when the note is released, it will be skipped and the envelope will jump immediately to the sustain decay segment. If a long delay is set, and the envelope has not reached the attack segment before the note is released, the envelope will remain at 0. However, if Freerun is turned on, the envelope will continue through the delay, attack, decay and sustain segments and remain at the sustain decay segment. This is exactly the same as holding down the note on the keyboard. When the Sustain Pedal parameter is turned off, the Sustain Pedal will have no effect on the envelope.

Level (00 to 99)

This is the overall output level of the envelope. If this is set to 00, the FENV will have no output and will have no effect, while at 99 it will have a maximum effect on whatever it is being routed to. Tip: When selecting FENV Level as a modulation destination, set the FENV level to 00 if the Modulation Level is above 0 (or, set the FENV level to 99 if the Modulation Amount is below 0).

Velocity Modulation (00 to 99)

This determines how keyboard dynamics will affect the envelope level. When set to 99, note velocity controls the envelope’s output; notes played hard will deliver a higher envelope output than notes played soft. When set to 0, note velocity will have no effect on the envelope’s output level.

Amp Envelope

Amp Envelope (Page 1)

The Amp Envelope is crucial for all sounds because it sets the basic characteristics of the note--whether it attacks quickly or slowly, sustains or decays. Some Programs may leave the Amp Envelope in a sustaining mode, and provide attack and decay using the Filter Envelope; the effect is slightly different. Unlike Pitch and Filter Envelope, the Amp Envelope is always fully active (there is no second-page to the AMP function adjusting how much envelope is applied to the amp).

Attack (00 to 99)

This is the amount of time the envelope will take until it reaches its maximum output level. Setting the Attack to 0 will give a sharp edge to the sound (if the Delay is also set to 0 in AENV
