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 foot controller. 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 foot controller. 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 foot controller. 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 foot controller is applied, and minus ("") settings produce a decrease in level when the foot controller is applied. 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 foot controller. Plus "+" settings produce higher cutoff frequencies in response to foot controller operation - i.e. the more the foot controller is depressed, 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 foot controller 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. 86 VOICE EDIT MODE / 6:Controller
