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 Page 2--see below); a setting of 99 will result in a much slower
attack, taking many seconds before the envelope gets to maximum.
Decay & Sustain (00 to 99)
As soon as the attack portion of the envelope finishes (when the level reaches
maximum), the envelope will decay (decrease in level). The level it reaches is set by
the Sustain control; how long it takes to get there is set by the Decay control. In the
special case where the Sustain level is all the way up (99), then there is no decrease
and the Decay time segment is bypassed. Whatever level the sustain is set to is the
level that the decay section of the envelope will head for. Depending on the setting of
the Sustain Decay control (see below), the envelope will either hold at the sustain
