The C106 Dual Loopable VC AD Envelope & more
it’s a really versatile module. It’s not only a Dual Voltage
Controlled Attack / Decay envelope, it’s also a dual VC
LFO, an audio generator, a complex contour generator, a
dual pulse delay, a voltage controlled AD envelope with
adjustable delay and more….
The core of this module are two loopable voltage
controlled Attack / Decay envelopes that can be
interconnected in dierent ways to create dierent
functions.
Connection modes:
1 - Two independent Attack / Decay envelopes ( single
shot or looping )
2 - Envelope A triggers the Envelope B after reach the
end of the Attack phase
3 - Envelope A triggers the Envelope B after reach the
end of the Decay phase
4 - Envelope B triggers the Envelope A after reach the
end of the Decay phase
5 - Envelope A triggers the Envelope B after reach the
end of the Attack phase and Envelope B triggers Envelope
A after reach the end of the Decay phase
6 - Envelope A triggers the Envelope B after reach the
end of the Decay phase and Envelope B triggers Envelope
A after reach the end of the Decay phase
Each envelope has four manual controls,
Attack/Decay time and Attack/Decay shape, continuously
variable from exponential to logarithmic. The A/D times
can be voltage controlled using the three available
modulation inputs, one for the Attack time, one for the
Decay time and one that controls the Attack and Decay
times simultaneously.

Attack / Decay times without voltage control:
Exponential Attack : from 0.5 ms to 7.5 s
Logarithmic Attack : from 5.5 ms to 68 s
Exponential Decay : from 4 ms to 10 s
Logarithmic Decay : from 37 ms to 94 s
Each envelope has an envelope output (0 to 5V), a bipolar output ( +/-5V ), an END pulse output (outputs a short
pulse every time the envelope reach the end of the Decay stage) and a gate/trigger input.
There are also another two common outputs with special functions :
A+B output: outputs the addition of the Envelope A and Envelope B. This function is really useful to
create complex envelopes.
A-B output: outputs the subtraction of the Envelope A and Envelope B. Using this output you can get
inverted envelopes, complex waveforms…

A CV ( Envelope B )
Attack Time CV input. This signal is added to the Attack Time set by
the Attack B potentiometer. This input accepts positive and negative
signals (+/- 5V). A positive signal results in longer attack times and a
negative signal results in shorter attack times.

LOOP ON/OFF SWITCH ( Envelope B )
Loop mode: After reach the end of the Decay phase the envelope
restarts automatically.
Single Shot mode: After reach the end of the Decay phase the enve-
lope remain at 0 Volts until another trigger/gate signal is received.

D CV ( Envelope B )
Decay Time CV input. This signal is added to the Decay Time set by
the Decay B potentiometer. This input accepts positive and negative
signals (+/- 5V). A positive signal results in longer decay times and a
negative signal results in shorter decay times.
A+D CV ( Envelope B )
Attack and Decay Time CV input. This signal is added to the Attack/
Decay Time set by the Attack B and Decay B potentiometers. This
input accepts positive and negative signals (+/- 5V). A positive signal
results in longer attack/decay times and a negative signal results in
shorter attack/decay times.
GATE A
Envelope A Gate input. This input is used to starts the envelope. The
envelope is a AD type so it doesn't matter if the signal received is a
gate or a trigger. The envelope can be re-triggered at every moment
of the Decay phase, if a Gate/Trigger signal is received during the
Attack phase this signal will be ignored.
GATE A
END A
End of Envelope A Pulse Out. A short pulse will be delivered every
time the Envelope A reach the end of the Decay Phase. This pulse can
be used to trigger envelopes, restart LFOs ....
END A
ENVELOPE A BIPOLAR OUTPUT
This output provides a bipolar version (+/-5V) of the Envelope A . This
signal can be used as VC LFO, Audio Generator or even adding oset
as 10Vpp envelope. If no envelope signal is pressent, this output will
remain at -5V so it can be use as voltage source.
