Option to separate midi by instruments #38

Closed suntong closed 12 months ago

suntong commented 1 year ago

Please add an option to jianpu-ly so as to separate midi files by instruments.

Take this Demo2.jp file for example, the generated midi file seems to have two instruments combined into one file, which might be for the most cases, however, it'll be good that we can have separated midi files for different instruments. As we need Soprano / Alto etc to have their own tunes.

Thanks

Lilypond already puts each instrument into a different channel / track, but as it's more convenient just to play the whole MIDI file without loading up some MIDI sequencer software to isolate a channel or track, we can easily get it to generate separate MIDI files as well.

So with the latest version if you put PartMidi in the score, you should get output.midi for all parts, output-1.midi for the first part only, output-2.midi for the second part only, etc. (This numbering will be different if you also have more than one score in the input.)
