Creating complex envelopes
A combination of the Clock Divider / Sequencer (A-
160/161) and a number of A-170 slew limiters can
produce complex envelopes (see Fig. 5).
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 further elaborate on this patch, 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).
