Recently I baught an Akai LPK 25 USB Midi-Keyboard that ships with a nonfree
software that allows you to configure the device. But I was able to reverse
engineer the communications protocol that is used by the device in about an
hour. Additionally it comes with a rebate on Ableton Live, which is nonfree
too.
Some months ago I baught a USB-Microphone which comes with a nonfree
recording software for Windows. However you can use free software such as
Audacity or OREMO for recording your UTAULOID. But OREMO is trapped by
Windows, so I can't use it.
Reverse engineering the LPK25 Editor sysex messages
Use the following command to dump midi messages sent by the nonfree program:
amidi -p virtual -d
