Sonic Pi binds MIDI codes to symbols like `:a4` for their corresponding note names, if that helps. It's not comprehensive -- there are no entries for doubled flats/sharps, for instance -- but you can write basic chords/melodic lines with a pretty limited need for numbers. You'll still need some for `sleep` (or `play_pattern_timed`), but if we're being pedantic about it, note lengths are already numbers as is.
