Projects / Rumor


Rumor is a realtime monophonic (with chords) MIDI keyboard to Lilypond converter. It receives MIDI events, quantizes them according to its metronome on the fly, and outputs intelligently handwritten-like corresponding Lilypond notation. Tempo, meter, key and other parameters can be set via commandline options. Rumor can use ALSA/OSS or emulate MIDI input with computer keyboard. It is scriptable with Guile. It has been tested on several major J. S. Bach organ pieces (see links to Mutopia in the documentation).

      Release Notes: This release adds chord (simultaneous notes) support (not to be confused with true polyphony) which can, in certain cases, save a lot of typing. Further, metronome beats can be newly customized (instrument, velocity, etc.) with Guile scripting.
