.ATTACK
(Rate)
T
he
parameter controls how long it takes for the VCF
EG output voltage to rise from
ze
ro to its maximum
level.
• DECAY (Rate)
This parameter controls how long ii takes for
VCF
EG
output voltage
to
fall from its maximum
lev
el (after
an
at-
tack time) to the break point level.

This envelope generator controls
the
"con-
tour"
(or changes over time,
in
terms
of
the
sound's attack, sustain, decay,
and
other
dynamic characteristics)
of
each program-
med sound. The " voltage changing over
time"
generated by
the
VCF
EG
is
controlled
by
the
parameters
"3
4 POLARITY"
and
"35
EG INT"
and
, then, modulates VCF
cutoff
frequencies to create " timbre changes over
time
."
(See POLARITY and
EG
INT
on
page
21.) The
output
voltage
of
VCF
EG
is
deter-
mined
by
the following
parameters
.
