Not bad! Free, open source and does everything I need it to do. Perfect for playing back little MIDI passages that are embedded into websites like Wikipedia.

Does what it says on the tin. Can't seem to play a midi file in its own tab, but if you just click on a midi link on a web page the player pops up and it starts playing, so that's good enough for me. Works great!
