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 (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
