Horizontal Crossfader

Horizontal Crossfaders allow for variable parameter control with commands being sent when the value of the slider is changed.

The default range for sliders is dependant on the control method.

  • Sliders with MIDI control methods will output a maximum range of 0 to 127. The upper value is adjusted using velocity parameter.
  • OSC and HTTP control methods will output a default range of 0 to 1 or -1 to 1 (mode dependant). The Multiplier Value will act as the range multiplier.
  • Horizontal Crossfaders declare the lower value to be the left position and upper value the right position of the slider handle.
