Standalone (MIDI) mode
The Launchkey MK3 powers up into Standalone mode. This mode does not provide specific
functionality for interaction with DAWs, the DAW in / out (USB) interface remains unused for this
purpose. However, to provide means for capturing events on all the Launchkey MK3
’s buttons, they
do send MIDI Control Change events on Channel 16 (Midi status: BFh, 191) on the MIDI in / out (USB)
interface and the MIDI DIN port:
Decimal:
Hexadecimal:
When creating Custom Modes for the Launchkey MK3, keep these in mind if you are setting up a
Custom Mode to operate on MIDI Channel 16.
