The Parameters
AMPLIFIER
ATTACK Determines the amount of
time it takes for the amplifier
envelope to rise to its maximum
level. The higher the ATTACK value,
the longer it takes for the envelope
to rise to maximum volume after
the start of a note.

DECAY Determines the amount of
time it takes for the amplifier
envelope to fade out. The higher
the DECAY value, the longer it
takes for the envelope to fall from
its peak level to the SUSTAIN value.

SUSTAIN Sets a variable level value
for the amplifier envelope at which
it remains after the end of the
DECAY
for the amplifier envelope at which
it remains after the end of the
DECAY
phase (see appropriate sec-
tion). The duration of the SUSTAIN
phase depends on the TIME value
(see appropriate section).
phase depends on the TIME value
(see appropriate section).
TIME Sets the bipolar time param-
eter for the amplifier envelope. It
determines the envelope’s
response once it reaches the SUS-
TAIN
eter for the amplifier envelope. It
determines the envelope’s
response once it reaches the SUS-
TAIN
level (see appropriate sec-
tion): If the knob is set to the
center position (12 o’clock) indi-
cated by the mathematical infinity
symbol, then the SUSTAIN level
remains constant through to the
end of the note; if you turn it
counter-clockwise to the left
(towards FALL), then the level
drops off at an increasing rate
towards the minimum level; If you
turn the knob clockwise to the
right (towards RISE), the level rises
at an increasing rate to maximum.

RELEASE Determines the speed or
rate at which the volume of the
amplifier envelope decreases after
the end of a note. The higher the
RELEASE

the end of a note. The higher the
RELEASE
value, the longer it takes
for the envelope to fall from its
current level to the minimum level,
when the key is released.
