ENVELOPE GENERATORS
The IMPLEXUS offers two envelope generators each with their own possibilities and purpose. The two envelope
generators are: MOD EG and AMP EG. We will detail them one by one, but first we will go through the common
envelope generator controls.
ABOUT ENVELOPES IN GENERAL: an envelope generator produes a varying control voltage signal with four time
specific curves: ATTACK, DECAY, SUSTAIN and RELEASE. The envelope generator is turned on by a gate signal, which
is generated when playing a MIDI note, for example.
ADSR
The IMPLEXUS envelope generators are both generating an ADSR slope/curve:
ATTACK
The ATTACK control sets the rise time of the envelope curve.
DECAY
The DECAY control sets the fall time from the end of the ATTACK curve to reach
the SUSTAIN level.
SUSTAIN
The SUSTAIN control sets the SUSTAIN level. When the ATTACK and DECAY
curve period is over, the envelope generator signal will stay at SUSTAIN level
for as long as the gate signal is high (for as long as a note is being held).
RELEASE
The RELEASE control sets the fall time, from the moment the gate is turned
off (note was released). The RELEASE curve will fall from any point in the
ATTACK, DECAY or SUSTAIN curve.

VELOCITY SENSITIVE
The envelope generators are “velocity sensitive”, which
means the maximum envelope signal level is set by
velocity level from MIDI. The amount of influence the
velocity level has on the envelope generator its output
can be set individually for each envelope generator using
the VEL AMT control.
VEL AMT
The VEL AMT (velocity amount) control sets the amount
of influence the velocity level has on the envelope gener-
ator. When the VEL AMT control is fully counterclockwise,
velocity does not influence the envelope generator output
at all. When the VEL AMT control is fully clockwise, you
will experience full velocity control. Velocity can be used
for amplitude: the softer you press a key (play a note), the
lower the audio volume and the harder you press a key
(play a note), the higher the audio volume. Velocity can
also be used for modulation depth: the harder you press a
key (play a note) the higher the depth of modulation.
NOTE:
Velocity is originally a MIDI parameter, but on the
IMPLEXUS it is also a voltage-controlled parameter.
There is a CV input for Eurorack, which allows you to do
amplitude modulation, for example.
MOD EG
The MOD EG (modulation envelope generator) can be
used for modulation purposes. It can modulate multiple
destination parameters: GLOBAL PITCH, HARMONICS,
FOLD and CUTOFF. The modulation envelope also has
a CV output on the back of the IMPLEXUS that can be
patched to any CV input.
The modulation envelope has a loop mode, so that it can
behave as an LFO triggered when gate is high. The LFO
period and curve is set using the ATTACK and DECAY
controls.
AMP EG
The AMP EG (amplifier envelope generator) controls
the VCA (voltage controlled amplifier) amplitude of the
IMPLEXUS. The amplifier envelope has a drone function
that sets the gate signal of this envelope generator to “al-
ways high/on” so you will have instant sound when the
SUSTAIN control is fully clockwise.
