Editing VL Voice Part Parameters
VL Part Parameter
The parameters below can be divided into the following two types: ones for selecting the controller
(Control Number) by which the parameter will be controlled and the others for setting the depth of the
parameter. Even though you have designated the controller, you cannot get audible changes if you set
the parameter to be controlled to 0 or around 0.
For the relationship between the control numbers and controllers see page 29.
IMPORTANT
When you use a sound card or a tone generator with no panel buttons...
To edit the VL part parameters you need to use a sequencing software and transmit the system
exclusive messages shown on the MIDI Data Format (p. 40), to the “mother” sound card/tone
generator.
Using the “XGworks lite,” properly installed in your PC (which is connected to the sound card/
tone generator) allows you to access almost all the VL part parameters (except for Filter EG
Depth) for VL-XG voices through the “XG Editor window.”
1
Filter EG Depth
FilEG Dept (Filter Envelope Generator Depth) ..................................... Settings: -64 … +63
The “FilEG Dept” parameter determines to what degree the amplitude/filter envelope generator
affects the filter's cutoff frequency. Higher values allow the envelope generator to vary the filter
cutoff frequency over a wider range.
2
Pressure
Prs CC No. (Pressure Control Change Number) ................ Settings: off … 95, AT, VEL, PB
“Pressure” corresponds to the amount of breath pressure applied to a reed or mouthpiece, or the
speed of the bow applied to a string. Pressure variations affect both volume and timbre. The “Prs
CC No.” parameter specifies the controller to be used for pressure control. When set to “off” max-
imum pressure is applied at all times.
• Please note that pressure affects not only volume, but timbre and pitch as well. Accurate keyboard/controller
pitch is produced only at maximum pressure.
