NG-VCF-VCA
You're already
familiar
with
this patch. We
give
it
a separate
numbering
here
so that you
have a place to file
notes
on particular
control settings and
control voltages you find useful.
out
5.13 RM-VCF-VCA
Up
to
this
point you have not used the Ring Modulator. We
insert this heading, under which the Ring Modulator is used only
with AC coupling and is
fed
with two oscillators at audio
frequen-
cies, to provide
you
with an excuse
for investigating
this traditional
function, and
a
place to make notes on
the
main
general results of
ring
modulation. Begin
with
the two
prewired
input
signals from the
VC01
sawtooth
and
the VC02
sine, and let
the
signal
from
the
mod-
ulator pass unfiltered
directly through the
VCF
to the Mixer. (Note
that
our prewired connections
would
also
allow
you
to
bypass
the
VCF
entirely
by
utilizing
the prewired RM-VCA input
and
then
opening
the VCA-Mixer
input rather than
the
VCF-Mixer input.)
