music - Chords in MIDI? -

-

i'm looking way represent chords in midi file.

note i'm not looking represent chord voicings. can trivially done multiple note-on messages. if that, have sort of note-on chord analysis every time read midi file in, , that's major nuisance since know chord structures when write file.

rather, i'm looking more akin guitar tablature or fake books. is, want record "c" or "cm" or "i" or "i" or “iii7" @ particular point in time.

so questions...

is there standard way this? (i'm not finding one, don't know current spec thoroughly.)

is there non-standard way of doing this?

i'm considering using "tag" facility of lyric/display meta event. appears though can invent {@chord=cm} , should transparent reader, past, present, or future, doesn't understand usage. reading standard right? reasonable, private, non-standard extension?

the midi specification provides values such "note on" , "pitch value" (as seen here) represented integers.

depending on midi type (there 3), should able save chord values way suggested. karaoke files created way.

if using windows, try noteworthy composer. link contains suggestion playback.
