Envelope page
The Envelope page is opened by clicking the ENV button
at the top of the lower half of the control panel. The page
contains all parameters and the modulation and velocity
destinations for the four independent envelope genera
-
tors.
Envelope generators govern how a parameter value
changes when a key is pressed, when a key is held and
finally when a key is released.
On the Envelope page, the parameters for one of the four
envelope generators is shown at a time.
• You switch between the four envelopes in the section to
the left.
Clicking on either of the four mini curve displays 1 to 4 selects it and dis-
plays the corresponding envelope parameters to the right. The mini curve
displays also reflect the envelope settings for each corresponding enve
-
lope.
• Envelope generators have four parameters; Attack, De-
cay, Sustain, and Release (ADSR).
See below for a description of these.
• You can set envelope parameters in two ways; either by
using the sliders or by click-dragging the curve in the En-
velope curve display.
You can also do this in the mini curve displays.
• By default Envelope 1 is assigned to the master volume,
and therefore acts as an amplitude envelope. The ampli
-
tude envelope is used to adjust how the volume of the
sound changes from the time you press a key until the key
is released.
If no amplitude envelope were assigned, there would be no output.
• Envelope 2 is by default assigned to the Level parameter.
See “Level” on page 94.
The Envelope parameters are as follows:
Attack
The attack phase is the time it takes from zero to the max-
imum value. How long this takes is governed by the Attack
setting. If the Attack is set to “0”, the maximum value is
reached instantly. If this value is raised, it takes time before
the maximum value is reached. Range is from 0.0 millisec
-
onds to 91.1 seconds.
Decay
After the maximum value has been reached, the value starts
to drop. How long this takes is governed by the Decay time
parameter. The Decay time has no effect if the Sustain
parameter is set to maximum. Range is from 0.0 millisec
-
onds to 91.1 seconds.
Sustain
The Sustain parameter determines the level the envelope
rests at after the Decay phase. Note that Sustain repre-
sents a level, whereas the other envelope parameters rep-
resent times. Range is from 0 to 100.
Release
Release determines the time it takes for the value to fall
back to zero after releasing the key. Range is from 0.0 mil
-
liseconds to 91.1 seconds.
Punch
When Punch is activated, the start of the decay phase is
delayed a few milliseconds (the envelope “stays” at top
level for a moment before moving on to the decay phase).
The result is a punchier attack similar to a compressor ef
-
fect. This effect is more pronounced with short attack and
decay times.
Retrigger
When Retrigger is activated, the envelope re-triggers
each time you play a new note. However, with certain tex
-
tures/pad sounds and a limited number of voices it is rec-
ommended to leave the button deactivated, due to click
noises that might occur, when the envelope is ended up
abruptly. This is caused by the incoming re-trigger that
forces the envelope to start over again.
