Fmod (Frequency modulation depth) Range: 0 ... 127 Controls: [CS6], [-1] [+1], Dial Sets the maximum depth of filter cutoff frequency modulation (wah-wah type effects) applied via the modulation wheel. A setting of "0" allows no frequency modulation, while a setting of 127 results in maximum frequency modulation. When setting up the LFO (low-frequency oscillator) to apply cutoff modulation, this parameter must be set to a value other than "0" if cutoff modulation is to be applied via the modulation wheel. Also, the filter "CTRL" parameter (page 68) must be set to "LFO" in order to vary the cutoff frequency continuously. EGBs (EG bias depth) Range: -127 ... +127 Controls: [CS7], [-1] [+1], Dial Sets the depth and "direction" of EG bias produced by the modulation wheel. EG bias increases or decreases the amplitude envelope generator levels, simulating the dynamic variations that can be produced on an acoustic instrument more accurately than simple volume control. A setting of "0" produces no change in EG levels. Plus ("+") settings produce an increase in level when the modulation wheel is rolled upward, and minus ("-") settings produce a decrease in level when when the modultion wheel is rolled upward. The greater the value, the greater the change in level. Coff (Cutoff frequency depth) Range: -127 ... +127 Controls: [CS8], [-1] [+1], Dial Sets the maximum depth of filter cutoff frequency variation applied via the modulation wheel. Plus "+" settings produce higher cutoff frequencies in response to modulation wheel operation - i.e. the higher the modulation wheel position, the higher the cutoff frequency. The maximum setting of "+127" produces the maximum cutoff variation. Minus "-" settings produce the opposite effect: lower cutoff in response to higher modulation wheel positions. A setting of "+0" results in no cutoff variation. The filter "CTRL" parameter (page 68) must be set to "LFO" in order to vary the cutoff frequency continuously. 84 VOICE EDIT MODE / 6:Controller

Fmod (Frequency modulation depth)
Range: 0 … 127
Controls: [CS6], [-1] [+1], Dial
Sets the maximum depth of filter cutoff frequency modulation (wah-wah
type effects) applied via the modulation wheel.
A setting of “0” allows no frequency modulation, while a setting of 127
results in maximum frequency modulation.
When setting up the LFO (low-frequency oscillator) to apply cutoff modula-
tion, this parameter must be set to a value
other than “0” if cutoff modulation
is to be applied via the modulation wheel. Also, the filter “CTRL” parameter
(page 68) must be set to “LFO” in order to vary the cutoff frequency continu-
ously.
EGBs (EG bias depth)
Range: -127 … +127
Controls: [CS7], [-1] [+1], Dial
Sets the depth and “direction” of EG bias produced by the modulation
wheel. EG bias increases or decreases the amplitude envelope generator levels,
simulating the dynamic variations that can be produced on an acoustic instru-
ment more accurately than simple volume control.
A setting of “0” produces no change in EG levels. Plus (“+”) settings
produce an increase in level when the modulation wheel is rolled upward, and
minus (“-”) settings produce a decrease in level when when the modultion
wheel is rolled upward. The greater the value, the greater the change in level.
Coff (Cutoff frequency depth)
Range: -127 … +127
Controls: [CS8], [-1] [+1], Dial
Sets the maximum depth of filter cutoff frequency variation applied via the
modulation wheel.
Plus “+” settings produce higher cutoff frequencies in response to modula-
tion wheel operation — i.e. the higher the modulation wheel position, the
higher the cutoff frequency. The maximum setting of “+127” produces the
maximum cutoff variation. Minus “-” settings produce the opposite effect: lower
cutoff in response to higher modulation wheel positions. A setting of “+0”
results in no cutoff variation. The filter “CTRL” parameter (page 68) must be
set to “LFO” in order to vary the cutoff frequency continuously.
