The C111 Multimode Contour Generator is a quad
analogue envelope generator and modulation source. It
can be congured to create dierent kind of envelopes,
from AD to ADSR and many more.
The module is composed by four identical envelopes with
two operation modes :
- AD : Attack - Decay
- ASR : Attack - Sustain - Release
These envelopes can be combined by pairs to create
envelope shapes that are not possible using a regular
envelope generator. Up to six dierent envelopes are
available at the same time.
Other important feature is that each envelope can be set in
loop mode.This opens the possibility to use the envelopes
as a LFO. The frequency range goes from 60Hz to one cycle
every 15 seconds. It’s also possible to combine two
envelopes in loop mode to generate complex modulation
signals.
C111 main characteristics :
- Four independent envelopes with AD and ASR modes
- Each envelope can be set in Loop mode independently
- Attack time from 1mS to 5 seconds
- Decay time from 20 mS to 10 seconds
- Gate A-B and Gate C-D are internally connected
- Up to six envelopes available at the same time.
All this features make the C111 Multimode Contour
Generator a really versatile module that can be used in
every patch in your system.

Operation Modes
AD
In this mode the gate length is irrelevant. Once the gate signal is received the envelope will raise until
reach 5V and then will start to fall to 0V. In this mode the envelope can be re-triggered at any moment
of the Decay phase but if a gate signal is received during the Attack phase it will be ignored.
All four envelopes in the module have two basic operation modes selectable by one switch in the front
panel. This two modes are AD ( Attack / Decay ) and ASR ( Attack / Sustain / release ). The envelope will
behave dierent depending witch operation mode is selected.

When the loop switch is activated the envelope will start to cycle between the attack and decay phase
without the need of a gate signal. The envelope can be re-triggered at any moment of the Decay phase
but if a gate signal is received during the Attack phase it will be ignored. If the loop mode is disconnec-
ted during the Attack or Decay phase, the envelope will complete its full cycle and it will remain at 0V
until a new gate is received or the loop mode is activated.

ASR
In this mode when a gate signal is received the envelope will raise until reach 5V and it will remain at
that level as long as the gate signal is active. After that, the envelope will start to fall to 0V. In case the
gate length is shorter than the Attack time, the envelope will start to fall to 0V as soon as the gate is
removed. In ASR mode the envelope can be re-triggered at any moment of the Decay phase.
When the loop switch is activated the envelope will start to cycle between the attack and decay phase
without the need of a gate signal. In case a gate signal is received during the Attack phase, the envelope
will raise until reach 5V and it will remain at that level as long as the gate signal is active. In case the gate
length is shorter than the Attack time, the envelope will start to fall to 0V as soon as the gate is removed.
The envelope can be re-triggered at any moment of the Decay phase. If the loop mode is disconnected,
the envelope will start to fall to 0V it will remain at that level until a new gate is received or the loop
mode is activated.

ADSR ( Attack - Decay - Sustain - Release )
The more typical synthesizer envelope. To obtain an ADSR, one envelope has to be set to AD and the
other to ASR. Attack times should be the same in both envelopes. The Decay time is determined by
the AD envelope and the release time by the ASR envelope. The BALANCE knob sets the Sustain level,
the more ASR envelope ( in this case B ) the sustain level will be higher. The only dierence with a
normal ADSR is that in case the gate signal is removed before the end of the attack phase , the AD
envelope will complete anyway its full cycle .
ADASR ( Attack - Decay - Attack - Sustain - Release )
This is a variation of the ADSR envelope. It has an Attack-Decay phase followed by a second Attack
until reach the Sustain level. As before one envelope has to be set to AD and the other to ASR. The
Attack and Decay time of the AD envelope should be short, especially the Decay time. In total the AD
envelope has to be shorter than the Attack time of the ASR envelope. The BALANCE knob sets the
Sustain level but it also aects the Attack phase, with more ASR envelope the rst Attack-Decay
phase will be less accentuated.

Gate
USING THE MIX OUTPUTS ( A+B , C+D)
One of the more interesting features of the C111 is the possibility to combine two envelopes to
create new envelope shapes. Using the A+B and C+D outputs is easy to obtain envelopes not possi-
ble using a normal envelope generator. This section explain how to set up the module to create those
kind of envelopes. The knobs in the examples, are set to obtain the envelope times shown in the
graphics. Shorter or longer times are possible for every kind of envelope. Since these envelopes are
obtained adding and subtracting signals, some of them will not reach the typical 5V peak. The
graphic resolutions are, vertical 2 volts/division and horizontal 1 second/division.

AADSR ( Attack - Attack - Decay - Sustain - Release )
This is another ADSR variation. This envelope has two Attack sections, the rst one faster than the
second one. As in the previous examples, one envelope has to be set to AD and the other to ASR. To
obtain the two attack phases, the Attack of the AD envelope has to be longer than the Attack time of
the ASR envelope. The Decay time is determined by the AD envelope and the release time by the ASR
envelope. The BALANCE knob sets the Sustain level, the more ASR the higher will be the sustain.It
also sets the break point of the two Attack phases.

Gate
AASR ( Attack - Attack - Sustain - Release )
This envelope has two Attack sections, the rst one faster than the second one, followed by a sustain
and release sections. To obtain this kind of shape both envelopes have to be set to ASR and they must
have dierent Attack times and the same Release times. The BALANCE knob sets the break point of
the two Attack phases.
Envelope
Gate
ASRR ( Attack - Sustain - Release - Release )
This envelope has an Attack and Sustain phases followed by a two Release sections with the rst one

they must have the same Attack times and the dierent Release times. The BALANCE knob sets the
break point of the two Release phases.

AASRR ( Attack - Attack - Sustain - Release - Release )
This envelope has two Attack sections followed by Sustain phase and two Release sections. The rst
Attack and Release sections are faster than the second ones. To obtain this kind of shape both envelo-
pes must be set to ASR and they must have dierent Attack and Release times. The BALANCE knob
sets the break point for the Attack and Release phases.
Envelope
Gate
ADD ( Attack - Decay - Attack - Decay )
This envelope is a combination of two AD envelopes. The Attack and Decay time of rst AD envelope
should be shorter than the Attack time of second AD envelope. The BALANCE sets the amount of
each envelope present in the nal envelope. Since they are both AD envelopes the gate length is not
important.
Envelope
Gate
ADD ( Attack - Hold - Decay )
This envelope has an Attack phase followed by a Hold time and a Decay phase. To obtain this shape
both envelopes must be in AD mode. The Attack time of the rst envelope must be equal to the
Release time of the second one. In the same way the Attack time of the second must be equal to the
Release time of the rst envelope. The BALANCE knob should be more or less in middle position .
