Cacophony is a minimalist and ergonomic MIDI sequencer. It's minimalist in that it doesn't have a lot of functionality MIDI sequencers have. It's ergonomic in that there is no mouse input and a very clean interface, allowing you to juggle less inputs and avoid awkward mouse motions.

Cacophony is open source. You can buy it, or you can compile it for free.
