mid and midi

[Francois Planiol-Auger]

Hi!
I am searching how to convert *.mid to ly. (mainly from tobis-notenarchiv.de
I wrote already about, but I dont still have a working solution.

It seems to me that mid and midi very different file-formats are.
See in PS.
With
> midi2ly file.midi (from mutopia)
... works fine 
but not with midi2ly file.mid. (from tobis-notenarch...)
I get then a not usable file.ly
(I got these 2 files of the same choral from bach in mid and midi for test)

I tried/searched till now:

- First way: convert mid2midi then midi2ly (look for differences in PS)
I found a script mid2midi*, but unfortunately it is a matlab script, so I cant 
use it. Matlab doesnt seems to have much contact with private persons...

- Second way:
open file.mid with noteedit then export as lilypond and purify the .ly 
file!!!... Very heavy. Not practicable for the many files I have to handle. 
But if there is no other solution...

- Third and best way, but how?
mid2ly
I found an advice in sourceforge.jp** that there was either a mid2ly and a 
midi2ly. Is that true? How to convert from mid? Unfortunately, I cant 
understand Japanese...

- ThirdA: it would be helpful, of course, to have a cap2ly, but it seems to be 
a difficult topic ;-) or is it not?

Of course, I want to convert pieces that do only in this .mid format exist. 
For BWV734, I dont need that anymore ;-)

That it for now. I hope my english is human readable ;-)

Thanks

Francois

BWV734.ly (imported and exported from .mid through noteedit (who says: done, 
but there are problems:
Noteedit hat die Partitur nach LilyPond exportiert. Aber es gibt
einige Probleme, die ein erfolgreiches Arbeiten von LilyPond verhindert.
-----------------------------------------------------
Zeile 1; Takt 1 hat 0: 128tel; es sollten aber 128 sein
Zeile 1; Takt 1 hat 0: 128tel; es sollten aber 128 sein
Zeile 1; Takt 1 hat 0: 128tel; es sollten aber 128 sein
Zeile 1; Takt 1 hat 0: 128tel; es sollten aber 128 sein
etc etc etc

Dont laugh !-)
using afterward the convert-ly doesnt really helps
