Program Changer is a super simple tool to send and receive MIDI Program Changes. The big keypad allows for quick entry to switch your synthesizer patches, audio mixer presets, lighting desk scenes, or whatever you can link to a MIDI Program Change command. Use the plus and minus keys to quickly jump up and down. Alternatively, Program Changer can just give you a big display of incoming Program Change numbers in 'receive' mode. Program Changer sends and listens to all MIDI devices or network sessions available. I'm seriously considering Audiobus support for inter-app MIDI commands. Let me know if you need this, then I might hurry up. If you have any questions or feedback, don't hesitate to contact me directly via contact@oscarbouwmans.nl.
