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.
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 De-
cay time parameter. The Decay time has no effect if the
Sustain parameter is set to maximum. Range is from 0.0
milliseconds 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 by a few milliseconds (i.e. the envelope remains at
the top level for a moment before moving on to the decay
phase). The result is a punchier attack similar to a com
-
pressor effect. 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 textures/
pad sounds and a limited number of voices it is recom-
mended 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 en
-
velope to start over again.
Assigning Envelope modulation destinations
To assign a modulation destination for an Envelope, pro-
ceed as follows:
1. Click in the “Mod Dest” box for one of the Envelopes.
A pop-up menu appears in which all possible modulation destinations
are shown. All Sound parameters as well as most LFO and Envelope pa
-
rameters are available as destinations.
2. Select a destination, e. g. Filter Cut Off.
The selected modulation destination is now shown in the list. Beside the
destination, a default value (50) has been set. The value represents the
modulation amount.
