Envelope sections

There are three Envelope generators in the Voice section. These are the Amp enve-

lope, the Filter envelope and the Mod envelope. Each voice played has a separate en-

velope. There is also an additional Global Envelope which is described separately -

see page 215.

D The Filter envelope is pre-wired to control the frequency of Filter 1 and 2.

Note that envelope control of filter frequency can be switched off in each Filter

section (the Env parameter can be set to 0), so the Filter Envelope can be used to

control other parameters as well.

D The Amp Envelope is pre-wired to control the amplitude (volume).

Similarly, the Amp envelope can also be used to control other parameters, but in

the Voice section you cannot switch off or bypass the Amp Envelope - if no voice

is active (i.e. if there is no gate trigger input to the Amp envelope) there will be no

output from oscillators or any external audio source routed to the Voice section.

D The Mod Envelope can be freely assigned to control parameters.

This is done in the Modulation section.

Filter Envelope

The Filter Envelope is a standard ADSR envelope as used in the Subtractor.

D By setting up a filter envelope you control the how the filter frequency or

some other parameter should change over time with the four parame-

ters, 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 notes (which is the normal mode) and allow the envelope to be trig-

gered by some other parameter.

“Gate Trig” should normally be activated.

D The time ranges of each step are as follows:

Attack: 0 ms - 10,3 s / Decay and Release: 3 ms - 29,6 s. Sustain is not set as a

time but as a level (from Off to 0dB).

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 parame-

ters, 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 pa-

rameters:

Parameter

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 enve-

lope 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.
