I want to take MIDI input from a device (like a keyboard), change some parameters (f. e. add a pitch bend) and send the resulting MIDI output to a device (like a software synthesizer).
I’d like to have a open-source, cross-platform (Windows, Mac OS, Linux) solution in C/C++ or Java that makes it easy to
- list and select MIDI input/output devices
- send and receive messages to/from these devices
I don’t necessarily need functions that compose the messages (like a pitch bend function that returns
0xE16000 for a semitone up pitch bend on channel 1), I’d be able to do that myself.
Which one would you recommend? Why? Are there other, maybe better possibilities?
