Manufacturer Description: Module A-141 (VCADSR) is the voltage controlled version on
an ADSR type envelope
generator - a bit like the the voltage controlled version of the A-140. Whenever a gate signal is sensed
at the VCADSR's gate input, an adjustable sequence of voltages is triggered - the
envelope. You can then use these envelopes to modulate a VCO, VCF or VCA, or to
control any other voltage controlled parameter of an A-100 module, e.g.
Phasing A-125, Frequency-Shifting A-126,
BBD-Delay A-188-1/A-188-2 or
Waveshaping A-116/A-137.
The shape of the envelope is governed by four parameters: Attack, Decay, Sustain and
Release. On the A-141, these parameters can be controlled by hand, or by voltage control,
via the dedicated CV inputs (each with an attenuator).
The A-141 VCADSR also has a retrigger facility: while the gate is open, a trigger pulse
received at the retrigger socket will re-start the envelope from the beginning of its
attack phase.
The time range for A, D and R is about 3 ms ...
20 s. The module can be modified upon request (changing a capacitor) for another
time range, e.g. 300us... 2s.
