PITCH RATE
These parameters set the rate of pitch variation. Higher values
produce faster variation.
DECAY1, Set the rate of variation between the initial pitch
envelope level and the levels set by the PITCH
DECAY2,
LEVEL DECAY1, DECAY2, and DECAY3 param-
DECAY3
eters, respectively.
RELEASE Sets the rate of variation from the level at key-
release to the level set by the PITCH LEVEL
RELEASE parameter.

PITCH LEVEL

These parameters sets the pitch envelope level offset value.
INITIAL Sets the initial offset of the envelope.
DECAY1, Set the offsets after DECAY1, DECAY2, and
DECAY2,
DECAY3 variation.
DECAY3
RELEASE Sets the offset after PITCH RATE RELEASE
variation after key-release.

FILTER RATE

Set the rate of cutoff frequency variation. Higher values pro-
duce faster variation.
INITIAL Sets the length of time the initial filter envelope
level will be maintained. Higher values correspond
to shorter time.
DECAY1, Set the rate of variation between the initial filter
DECAY2, envelope level and the levels set by the FILTER
DECAY3 LEVEL DECAY1, DECAY2, and DECAY3 param-
eters, respectively.
RELEASE Sets the rate of variation from the offset at key-
release to the offset set by the FILTER LEVEL
RELEASE parameter when SUSTAIN is off.
SUSTAIN Sets the rate of variation from the offset at key-
release to the offset set by the FILTER LEVEL
SUSTAIN parameter when SUSTAIN is on.

FILTER LEVEL

These parameters set the amount of variation from the preset
cutoff frequency. Level "0" is the preset value.
INITIAL Sets the initial level of the envelope.
DECAY1, Set the levels after DECAY1, DECAY2, and
DECAY2, DECAY3 variation.
DECAY3
RELEASE Sets the level after FILTER RATE RELEASE
variation after key-release when SUSTAIN is off.
SUSTAIN Sets the level after FILTER RATE SUSTAIN
variation after key-release when SUSTAIN is on.
