MIDI is a system for control of digital music instruments. The MIDI standard also defines a file format to store such control data. MIDI treats music as a sequence of notes. Audio signal processing is not its purpose.
- MIDI files can be created and dissected by Haskell by the midi library. In the past this was integrated in Haskore. There is also a Darcs repository.
- You can do real-time MIDI processing on Linux through ALSA using the alsa package.
- You can also do that with the alsa-midi package, but it is no longer supported in favor of the alsa package.
- You can compile Haskore music into MIDI files.
