Envelope Panel Parameters
r
The Panel parameter controls of the Filters envelo-
pes and the amplifier envelope are almost identical.
Attack
Determines the attack rate or amount of time it takes for a
signal to go from zero to maximum level.
Decay
Determines the decay rate or amount of time it takes for a
signal to reach the
Sustain
level.
Sustain
Determines the sustain level that is held until a note ends.
Release
Once the note has ended, the release phase begins. During
this phase, the envelope fades to zero at the rate deter-
mined by the release value.
Velocity
Determines the amount of influence the corresponding
envelope has on the routed parameter – for example,
cutoff frequency for the filter envelope, based on key ve-
locity. This parameter works similarly to the
Amount
parameter with the difference that its intensity is velocity
based. Use this feature to give a more expressive character
to the sound. When you hit the keys smoothly only mini-
mal modulation is applied. Hit them harder, the modulati-
on amount increases likewise.
Amount (not for Amp Envelope)
Determines the amount of influence the corresponding
envelope has on the modulated parameter – for example,
cutoff frequency. For positive settings, the modulation is
increased by of the envelope; for negative settings, it is
decreased.
r
The overall modulation applied to the correspon-
ding parameter is calculated as the sum of both the
Amount
and
Velocity
parameters. Therefore, you
should always bear this total in mind – especially
when a filter does not behave as you expect. You can
also create interesting effects by setting one para-
meter to a positive and the other to a negative
amount.
