inside Minim library I found nice example of reading and playing MIDI file.  
I was thinking to make some algoritmic MIDI generator. But I cannot find any functioonality or example how to write MIDI file using Minim or other processing library.

There I found some library called SoundCipher from processing 1.0, which is veryold and I guess not working any more.

Have you seen [this](https://github.com/sparks/themidibus) one?

Aha, I overlooked it.  
It seems to be dedicated to communication with external MIDI hardware (like keyborad) which is not what I need. Nevertheless, they say it can also read/write MIDI files, but I don’t see example how to do it.

In the meantime I found [this example](http://www.automatic-pilot.com/midifile.html) how to write MIDI directly using `javax.sound.midi.*`which seems rather clear. Also they say _" MidiBus offers little functionality that isn’t available from Java’s native [javax.sound.midi package](http://docs.oracle.com/javase/6/docs/api/javax/sound/midi/package-summary.html)."_, so perhaps I stick to `javax.sound.midi.*`
