Semantic description of controllers to be operated by one respectively two-fingers:

  • onoff — one-DOF controller with two states: [on|off]
  • Button : onoff — Button (on/off) with snap back (push button)
  • linear — continuous one-DOF controller, keeps state
  • linearSnapper — one-DOF contiuous controller, snapping back into a fixed default position
  • Fader : linear — one-DOF Fader
  • Knob : linear — turning knob
  • composite — composite of several controllers
  • ThumbStick : composite — small two-DOF analogue joystick with additional knob-functionality

The above list is taken from a very early attempt of mine to work out differences in one-finger controllers in order to build JInT, a generic control system in SuperCollider.
