Joystick to ALSA MIDI Sequencer Converter
In fact it’s a really tiny piece of software that turns a joystick into a MIDI controller for the ALSA sequencer infrastructure. . Its original purpose was to test the MIDI interface of terminatorX but that turned out to be fun, so it made it here in the hope that it could be useful for other experiments. . For a more detailed description on what it does and how to use it have a look the manpage.
