Vector Fader
Vector faders function like joysticks—they can be moved in two dimensions: up/down
and left/right. Each dimension generates its own MIDI events, so each time you change
the position of the crosshair with the mouse, two MIDI events are sent.
Most faders have Input and Output definitions (see “Fader Functions: Range, Val As” on
page 946) which determine the MIDI events sent by the fader (Output), and those it
reacts to (Input).
The vector style fader replaces these with Vert and Horz definitions, which determine
the MIDI events that correspond to vertical and horizontal motion. If corresponding
MIDI events are received by the vector style fader, its crosshair display will update
accordingly.
4-Channel Vector Mode
If you set a vector fader’s Vert and Horz definitions to the same MIDI event (the same
MIDI controller and channel), the vector fader will send out four MIDI events each time
the crosshair is moved.
These will be the same MIDI event (a controller, for example), sent on four consecutive
MIDI channels, starting with the channel set in the Vert definition.
 Upper-left for the lowest channel (channel 3, for example)
 Upper-right (channel 4)
 Lower-left (channel 5)
 Lower-right (channel 6)
The values of these MIDI events corresponds to the proximity of the crosshair to the
vector fader’s four corners:
 In the center, all channels receive a value of 32.
 At the corners, the corresponding channel receives a value of 127 and all remaining
channels receive a value of 0 (if using the default range of 0 to 127).
