Creating complex envelopes
A small modification to the previous patch is shown in
Fig. 3. Here, the Clock Sequencer outputs are
connected to a series of Slew Limiters (A-170), to
create one very complex envelope.
The Clock Sequencer triggers the Slew Limiters in
sequence, and their various envelopes are mixed in a
linear mixer A-138a. The result is a complex envelope
which can be patched from the mixer output to
anywhere.
P
You can elaborate on this patch further, by
adding other control voltages to the slew
limiters’ envelopes - for instance:
• an ADSR with a long envelope, triggered
by output ! on the A-161;
• an LFO output, with or without reset;
• the random output from an A-118;
• an audio signal via an envelope follower
(A-119).

If you use more than four modulation sour-
ces (Slew Limiter, ADSR, etc.), you’ll need
two mixers.
