Modulation delay

The A-162 is particularly useful for delaying the onset
of modulation
, for instance of a VCF, VCO, VCA,
etc., by causing the gate to open later. It can also
create pseudo echo effects.

Fig. 2: Delayed vibrato

In the example in Fig. 2, the onset of vibrato (sub-
audio frequency modulation of a VCO) is delayed by
using the A-162 to delay the gate which will open the

VCA. By patching in an AR envelope (in this case an
A-170, but an A-140 could also do the job) the
intensity of the vibrato can increase and decrease
gradually.

Stereo "Echo"

The patch in Fig. 3 produces a sort of stereo echo.
When a key is pressed, the sound first comes out of
the Out

L

left VCA output, and then, after a delay set by

the A-162, the ‘echo’ comes out of the right VCA
output, Out

R

.
