Amp Envelope
The Amp Envelope is also a standard ADSR envelope.
D By setting up a Amp envelope you control the how the amplitude or some other parameter should change over
time with the four parameters, Attack, Decay, Sustain and Release.
Please refer to the Subtractor chapter for a description of these parameters.
D The “Gate Trig” button can be used to switch off the envelope triggering from note input (which is the normal
mode) and allow the envelope to be triggered by some other parameter.
“Gate Trig” should normally be activated.
D The ranges of each step are the same as for the Filter envelope.
Mod Envelope
This is a general purpose ADR (Attack, Decay, Release) envelope with a pre-delay stage before the Attack phase.
The Delay to Decay phase can also be looped. Apart from standard Attack, Decay and Release stages the Mod Env
has the following parameters:
Global section
The Global section contains parameters that affect all voices. It contains two effects, an open filter slot, the Global
Envelope and LFO 2.

Description
Delay This can set a delay before the onset of the envelope.
Loop If this is activated, the envelope phase from Delay to Decay will continuously loop.
Tempo Sync If this is on, each stage will have a length that corresponds to beat increments of the current
sequencer tempo. E.g. you can have a 1/4 delay before a 1/16 attack phase followed by a
1/8 decay. Each stage can be set a range from 1/32 to 4/1 (4 bars).
If this is off, the envelope times are free running and can be set in seconds (same time
ranges as for the Filter Envelope).
Gate Trigger The “Gate Trig” button can be used to switch off the envelope triggering from notes (which
is the normal mode) and allow the envelope to be triggered by some other parameter. “Gate
Trig” should normally be activated.
