1. Introduction
Module A-141 (VCADSR) is a voltage controlled
envelope generator.
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 and/or VCA, and
alter the input and output voltages of all sorts of
modules.
The shape of the envelope is governed by four para-
meters: Attack, Decay, Sustain and Release (see Fig.
1 on page 3). 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 (see Fig. 2 on page 5).
