PA G E 11 - FILTER E G
Here you can make settings for the EG that will produce
time-varying changes in the cutoff frequency of filters A and
B for the selected oscillator. The depth of the effect that these
settings will have on the filter cutoff frequency is determined
by the “Velocity” and “Intensity” parameters.
S elected
Use this parameter to select an oscillator to put in edit. Alter-
natively, you can select oscillators using the F1-F4 buttons.
Filter envelope
S tart/Attack/Break/ S ustain/Release Level
These are the envelope segment levels. The result will depend
on the filter that was selected in “Filter Type”. For example,
with the Low Pass Resonance filter, positive (+) values of EG
Intensity will cause the tone to be brightened by positive (+)
levels, and darkened by negative (–) levels.
-99…+99
Level value.
Start Level
This parameter specifies the change in cutoff frequency at the
time of note-on.
Attack Level
This parameter specifies the change in cutoff frequency after
the attack time has elapsed.
Break Point Level
This parameter specifies the change in cutoff frequency after
the decay time has elapsed.
Sustain Level
This parameter specifies the change in cutoff frequency that
will be maintained from after the slope time has elapsed until
note-off occurs.
Release Level
This parameter specifies the change in cutoff frequency that
will occur when the release time has elapsed.
Attack/Decay/ S lope/Release Time
These parameters specify the time over which the filter
change will occur.
0…99
Time value.
Attack Time
This parameter specifies the time over which the level will
change from note-on until the attack level is reached.
Decay Time
This parameter specifies the time over which the level will
change from the attack level to the break point level.
Slope Time
This parameter specifies the time over which the level will
change after the decay time has elapsed until the sustain level
is reached.
Release Time
This parameter specifies the time over which the level will
change after note-on occurs until the release level is reached.
Filter EG ‘Level’ modulation
AM S (L) (Alternate Modulation S ource)
This parameter selects the source that will control the “Level”
parameters of the filter EG (“AMS (Alternate Modulation
Source) list” on page 14-19).
Intensity (AM S Intensity)
This parameter specifies the depth and direction of the effect
applied by “AMS”. With a setting of 0, the levels specified by
“Frequency A (Cutoff Frequency A)” will be used.
For example, if “AMS” is Velocity, and you set “Start Level
Swing”, “Attack Level Swing” and “Break Level Swing” to +
and set “Intensity” to a positive (+) value, the EG levels will
rise as you play more strongly. If “Intensity” is set to a nega-
tive (–) values, the EG levels will fall as you play more
strongly.
-99…+99
Intensity value.
S tart Level S wing
This parameter specifies the direction in which “AMS” will
affect “Start Level”. When “Intensity” has a positive (+)
value, a setting of + for this parameter will allow “AMS” to
raise the EG level, and a setting of – will allow “AMS” to lower
the EG level. With a setting of 0 there will be no change.
Attack Level S wing
This parameter specifies the direction in which “AMS” will
affect “Attack Level”. When “Intensity” has a positive (+)
value, a setting of + for this parameter will allow “AMS” to
raise the EG level, and a setting of – will allow “AMS” to lower
the EG level. With a setting of 0 there will be no change.
Break Level S wing
This parameter specifies the direction in which “AMS” will
affect “Break Point Level”. When “Intensity” has a positive
(+) value, a setting of + for this parameter will allow “AMS”
to raise the EG level, and a setting of – will allow “AMS” to
lower the EG level. With a setting of 0 there will be no
change.
