Bank Buttons
 
The Bank buttons, situated in the top left corner of the X-Pro’s front panel, let you choose 
different banks of programs (e.g., KB3 programs or Classic Keys programs). Within each bank, 
you can use the Program and Category buttons (to the right of the display) to select individual 
programs. 
The Bank buttons have special functions in KB3 mode, indicated by labels beneath each button.
 
Sliders
 
In KB3 mode, the X-Pro’s nine sliders emulate an organ’s drawbars. For example, slider A 
emulates an organ’s 16’ drawbar. In other modes, the sliders can be used to send values for 
different MIDI controllers. In either case, you may have to move the slider past the current value 
for its selected function before slider movement will have any effect.
Most VAST programs use the sliders for these functions:
A Data Filter frequency, Brightness
B MIDI 13 Filter resonance, Tremolo rate control
C MIDI 22 Layer volume, Envelope control, Lo tonal balance
D MIDI 23 Layer volume, Envelope control, Hi tonal balance
E MIDI 24 Layer volume for thumps and release
F MIDI 25 Effects control 1
G MIDI 26 Effects distortion drive
H MIDI 27 Effects distortion warmth
I MIDI 28 Reverb / delay control
