About this Guide
This document provides all the information you need to be able to control the Launchkey MK3.
The Launchkey MK3 communicates using MIDI over USB and DIN. This document describes the MIDI
implementation for the device, the MIDI events coming from it, and how the Launchkey MK3
’s various
features can be accessed through MIDI messages.
MIDI data is expressed in this manual in several different ways:
-
A plain English description of the message.
-
When we describe a musical note, middle C is deemed to be ‘C3’ or n
ote 60. MIDI channel 1
is the lowest-numbered MIDI channel: channels range from 1 - 16.
-
MIDI messages are also expressed in plain data, with decimal and hexadecimal equivalents.
The hexadecimal number will always be followed by an ‘h’ and the decimal equiv
alent given
in brackets. For example, a note on message on channel 1 is signified by the status byte 90h
(144).
