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 DECAY 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 envelope at which it remains
after the end of the DECAY 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 envelope. It determines the
envelope's response once it reaches the
SUSTAIN phase (see appropriate section):
If the knob is set to the center position
(12 o'clock) indicated by the mathemati-
cal 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),
