Novation SysEx utilities.
Project description
xKey
xKey provides a set of Novation SysEx utilities. It was intended to allow easy encoding and decoding of SysEx firmware updates from Novation.
Although this project was designed to support FLKey and Launchkey devices, others Novation firmware updates may be compatible with these utilities. However only software for these devices has been tested so far.
This project was generated by reverse engineering the software update process used by Novation FLKey MIDI keyboards. As a result of this, the exact use and terminology used by Novation may differ from that reflected in this project.
:warning: Tampering with firmware updates may break your device!
Firmware updates encoded and decoded using this utility may result in an unusable and unrecoverable device. This tool is provided with no warranty or guarantees.
Installation
xKey can be installed directly from PyPi. xKey currently has no external runtime dependencies as it only utilises functions exposed by the Python standard library.
pip install xkey
Example Usage
Decode an input SysEx format firmware update into binary
$ xkey decode launchkeymk3-firmware-217.syx
