ENVELOPE CONTROL
OF THE VCF
Electronic Sounds
I.Wah-Wah Sounds
Electronic sounds particularly
associated
with
the
synthesizer are produced
by means
of the VCF RESONANCE control. Each
time
a
key
is
depressed,
a sound like the
word "wow"
is produced. This is done by
means of envelope control
of the VCF with
the RESONANCE control raised.
Set
the
VCO RANGE and
the VCF CUTOFF
FREQ
to produce the desired effects.
Also, try changing the
shape of the
envelope
to alter the speed and shape of the tone
color change.

The
Human Voice
The
VCF envelope switch allows
the
VCF
to
be
controlled
by
means of a
normal
envelope
(A-O
or inverted envelope!
V^"),
as desired.
The
settings below produce a sound
very
near
that of the human voice.
Since a
small change
in the VCF CUTOFF
FREQ
control can cause a rather
large change in
the sound
quality, you may have to
readjust
this
setting to get a sound you
like. The
AUTOBEND
control of the VCO and
the
delay vibrato both help
the effect
and
should be
adjusted to
suit your tastes.
