The Parameters
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 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 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
phase (see appropriate section). The
duration of the SUSTAIN phase depends
on the TIME value (see appropriate sec-
tion).
TIME Sets the bipolar time parameter for
the amplifier envelope. It determines the
envelope's response once it reaches the
SUSTAIN level (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),
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 enve-
lope decreases after 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.
