4. User Examples
The A-143-2 is suitable for all kinds of modulations where
envelope generators are used. Please refer to the manuals
of other envelope generators (e.g. A-140, A-141, A-142).
LFO / Master Clock
In this example unit# 1 is used as an LFO (EOD is patched
to the gate input via multiples). The controls A, D, S and R
are used to define the frequency, shape and lower level (S)
of the LFO signal. EOD of unit#1 is connected to the gate
inputs of unit#2...4 and works as a master gate signal.
The four channel example of A-143-1 can be realized with
the A-143-2 as well.
Cyclically triggered envelope generators
The EOD output of each unit is patched to the gate input of
the succeeding unit. The EOD output of unit #4 is patched to
the gate input of unit #1. If instead of this connection an
external gate signal is connected to the gate input of unit #1
the "sequenced" envelopes can be synchronized to this
signal.
By means of the universal vactrol module A-101-9 the
parameters A, D and R can be voltage controlled. Please
refer to the A-101-9 manual for details.
