Desfonema Sequencer is a tracker-inspired MIDI sequencer. It uses a pattern oriented design, with n tracks by pattern. It offers a piano roll editor for tracks, and a tabbed track interface for patterns. It features convenient keyboard shortcuts, a virtual keyboard, step and live editing, MIDI input (ALSA), and a text-based file format that is easy to edit manually or merge and better suited for version systems like Subversion.
