Knobs and buttons of the ADSR envelope section.
Button Knob/Button
Description
- - -
ATTACK
The attack time controls the timespan between the reception
of a gate signal (key press) and attaining the peak of the
envelope. Higher values rise up the volume or the filter
frequency slower than small values.
- - -
DECAY
The decay time controls the timespan between the peak and
attaining the Sustain level (level while holding the key). Short
decay values in conjunction with short attack times ensure
crisp and short envelopes. At high sustain levels, the decay
time has little e
ff
ect on the envelope shape and sound.
- - -
SUSTAIN
The sustain level controls which value is output while holding
a key. The sustain level starts after the attack and decay
phases and will not exit until the gate signal returns to 0
(equivalent to letting go of the keyboard key).
- - -
RELEASE
The release time indicates how much time the envelope takes
after the sustain phase to drop its level to zero.
By default, the envelope of the DELTA CEP A controls the filter frequency and
the VCA volume. If you press the [EG/GATE]-button of the VCA section, the VCA
will be disconnected from the envelope. The color of the button LED changes
from green to blue for visualization. The volume is now controlled by a GATE
signal. The gate opens when a key is pressed and closes when the key is
released. Sometimes this type of control is too abrupt. Therefore, the DELTA
CEP A allows to extend the attack time and the release time during GATE
operation of the VCA. These additional functions can only be accessed in the
GATE operation of the VCA via the [SHIFT] key:
SHIFT
VCA ATTACK
The attack time of the VCA Gate function can be slowed down
by adjusting VCA ATTACK while holding the [SHIFT] button.
SHIFT
VCA RELEASE
The release time of the VCA Gate function can be extended by
holding the [SHIFT] button & turning the VCA RELEASE knob.

GATE
The [GATE] button lets you manually trigger the envelope
when no keyboard is available.
SHIFT
HOLD/MORPH
TRIG
Hold down the [SHIFT] button and simultaneously push the
[GATE] button to freeze the envelope. This can come in handy
when you set a tone and have no hand free to press a key. In
Morph mode, you can setup a snapshot trigger for the
envelope with this button combo. Whenever the morpher
reaches a new snapshot, the envelope will get triggered.
SHIFT
DECAY
You can use the [SHIFT] button & decay knob to connect the
LFO output to the ADSR trigger input without plugging in a
cable. The envelope then runs in an auto-trigger mode
controlled by the the LFO speed. You will notice that the gate
time of the envelope trigger can also be changed with [SHIFT]
& Decay. Higher values set longer gate times.
