FILTER ENVELOPE

ATTACK
Determines the amount of time it takes for the
filter 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
filter envelope to fade out. The higher the DE-
CAY value, the longer it takes for the envelope
to fall from its peak level to the SUSTAIN value.
SUSTAIN
Determines a variable level for the filter enve-
lope at which it remains after the end of the DE-
CAY phase (see appropriate section). The
duration of the SUSTAIN phase depends on the
TIME value (see appropriate section).
TIME
Sets the bipolar time parameter for the filter en-
velope. It determines the envelope's response
once it reaches the SUSTAIN phase (see appro-
priate section): If the knob is set to the center
position (12 o'clock) indicated by the mathe-
matical 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 in-
creasing 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 vol-
ume of the filter envelope decreases after the
end of a note. The higher the DECAY value, the
longer it takes for the envelope to fall from its
current level to the minimum level, when the key
is released.

AMPLIFIER ENVELOPE

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 vol-
ume 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 enve-
lope to fall from its peak level to the SUSTAIN
value.
