This document provides all the information you need to be able to control the Launchpad X.
Launchpad X communicates using MIDI over USB. This document describes the MIDI implementation for the device, which can be used to control LEDs and access Launchpad X’s various features.
MIDI data is expressed in this guide in several ways:
-
A plain English description of the message.
-
When we describe a musical note, middle C is deemed to be ‘C3’ or note 60. MIDI channel 1 is the lowest-numbered MIDI channel: channels range from 1 to 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 equivalent given in brackets. For example, a note on message on channel 1 is signified by the status byte 90h (144).
