Hello,
I have a midi file that I wanted to convert into scores, but the
scores simply don't look right.
While I have a real (relatively long) song in the MIDI, I believe that
I can fully reproduce the problem with the following simple example:
\score {
\new Voice = "melody" {
\set Staff.midiInstrument = "accordion"
\time 3/4
\relative c' {
c4 c c |
c1 d4 e |
f4*5 g4 |
f2.~ | % becomes f4*5
f2 e4 |
d4*3 | % becomes d2.
c4 c2~ | % becomes c1
c2
}
}
\midi { \tempo 4 = 160 }
\layout {}
}
(I picked accordion because one doesn't hear the duration with piano.)
The idea is to make midi from the above example first (lilypond
test.ly), then convert midi to scores (midi2ly test.midi -o test2.ly)
and typeset again (lilypond test2.ly).
The resulting MIDI file sounds right, but the typesetting of it is
very strange. I get just a single quarter note printed out rather than
something that takes the duration of five times a quarter.
OK, that's probably expected when I consciously enter the above
syntax, but not after conversion from a MIDI file.
I noticed that the whole idea of the asterisk operator is to print a
single unit, but to prolong it in MIDI (or for other purposes). But
there's a lot of inconsistency:
- if I properly enter c2.~ c2, I get c4*5 from the midi conversion
- if I properly enter c2~ c2, I get c1 which is "forbidden" inside 3/4
- if I sloppily enter c4*3 which would typset in a very weird way, it
comes out OK after the conversion as c2.
None of that makes any sense to me.
Sure I can manually fix the resulting plain text file, but I was
wondering if there was really no better way to get this done properly
and automatically.
Thank you,
Mojca
