Warning! Dead Project Ahead!

As you've no doubt noticed, I've not been maintaining MIDIator for some time. Frankly, I published this gem out of a personal need that no longer exists, and then I lazily chose to neglect my obligation to the community. I apologize for the lack of maintenance.

I strongly recommend that you migrate to Ari Russo's unimidi library as soon as possible. It looks a lot nicer than MIDIator and it's actively maintained.

Thanks for the interest and support!



A nice Ruby interface to your system's MIDI services.

MIDIator was inspired by Topher Cyll's fantastic Practical Ruby Projects book. In it, Topher describes how to interact with the MIDI providers in OSX, Linux, and Windows. As I was reading the book, I noticed some things I would do differently, which got me thinking that maybe it would be valuable to package up my modifications to the book's code and release it as a gem.


  • Cross-platform system for MIDI output
  • Built-in softsynth (OS X only, so far)


$ [sudo] gem install midiator



Huge, huge credit goes to Topher Cyll, without whom I would have had to figure all of this crap out for myself. Apress also deserves some credit; they released all the source in their book under the MIT license. That's a big deal and you should buy their books.

Props also go to the folks who have contributed patches. In alphabetical order:
