14EnglishSlider(s)Launchkey 25 has one slider control, and Launchkeys 49 and 61 have nine.The single slider on the Launchkey 25 transmits a Master Volume message (CC=7). This slidercannot be used in InControl mode.On Launchkeys 49 and 61, the functions of sliders 1 to 8 will differ depending on whetherInControl mode is in use. In InControl mode, the sliders will act as faders in the DAW’s mixersection, controlling the track levels in a set of eight consecutively-numbered channels. In BasicMapping mode, each slider transmits a fixed MIDI CC message. See the MIDI tables frompage 19 onwards.ButtonsOnly Launchkeys 49 and 61 have control buttons. There are a total of nine, one under eachslider 5 . In InControl mode, buttons 1 to 8 will typically act as mute or solo buttons for theselected set of eight channels in the DAW’s mixer. In this case, the ninth button switches thefunction of buttons 1 to 8 between Mute and Solo. Note that Solo mode is indicated by theinternal LED. In Basic Mapping mode, each button transmits a fixed MIDI CC message.See the MIDI tables from page 19 onwards.Rotary controlsAll models have eight rotary controls 6 , which like the other Launchkey controllers, may beplaced in InControl mode, or used in Basic Mapping Mode. In InControl mode they wouldtypically act as pan controls for a set of eight channels in the DAW’s mixer section. In BasicMapping mode, each rotary control transmits a fixed MIDI CC message. See the MIDI tablesfrom page 19 onwards.Launch PadsAll models of Launchkey are equipped with a set of sixteen velocity-sensitive pads. Theirprimary purpose is to trigger percussive sounds, and to do so, the pads need to be set to BasicMapping mode. In this case, all data is transmitted on MIDI Channel 10. In this mode, the padsilluminate red when struck. If the pads are set to InControl mode, they can be used to triggerclips or loops with certain software (such as Ableton Live), but have no function with non-clip-based applications such as Logic Pro or Cubase (hence cannot be switched into InControlmode).
