Cutoff Eg - Yamaha SY99 Owner's Manual

The following diagram shows how the filter
cutoff frequency would be adjusted across the
keyboard for the values in the LCD above.
AFM ELEMENT DATA / AFM FILTER
Summary: The cutoff frequency of each filter can be
moved over time by its own EG to make the
tone change.
Procedure;
From: AFM element job directory (JUMP #248)
8. AFM filter
Select: 03:CutoffEG
filter 1 rates press
Fl (Fitl), F3 (Rate)
filter 1 levels press
Fl (Fitl), F4 (Lvl)
filter 2 rates press
F2 (Flt2), F3 (Rate)
filter 2 levels press
F2 (Flt2), F4 (Lvl)
Specify: filter EG parameters
The offset at each break point is added to the cutoff
frequency of 80. For example the offset at break
point 1 (El) is -4, so the resulting cutoff frequency

at El is 76. The resulting cutoff frequency is limited
to the range of 0...127.
This indicates whether you are editing the EG of
filter 1 or 2.
This indicates the displayed segment and range
of the EG graphic display. To change the display
range, hold SHIFT and press F1-F6 (xl, x2, x5,
xl0 x20, x50). To shift the display to a different
segment, hold SHIFT and press F7 or F8
(Segl...Seg4, Rel1).
The filter EG is graphically displayed.
R1-R4, RR1-RR2 (Keyon Rates, Release Rates
0...63): Keyon Rates 1-4 and Release Rates 1-
2 determine the speed of the filter EG. Higher
settings result in faster change.
RS (Rate Scaling -7...+7): Rate Scaling allows
the filter EG rates to be increased or decreased
depending on the key that is played. For positive
settings the EG rates will increase as you play
higher notes, resulting in shorter envelopes. For
negative settings the EG rates will decrease as
you play higher notes, resulting in longer
envelopes.
L0-L4, RL1-2 (Keyon Levels, Release Levels
-64...+63): Keyon Levels 0-4 and Release
Levels 1-2 determine how the filter EG will in-
crease or decrease the cutoff frequency specified
for the filter.
Sync: Press F6 to turn filter sync editing mode on
or off. For details, refer to
Rates and Levels: The levels of the filter EG do
not directly determine the cutoff frequency of the
filter, but rather adjust the filter cutoff frequency
you set in 8.1 Filter cutoff.
