midi repair [was:] mid and midi

[Francois Planiol-Auger]

Hi

Thanks to all who tried to help till now.

I tried also with a lute prelude (the first one on this lute page @tobis). The 
problem remains.
But now, I know why.

All these Midi-files where certainly done using quantization. During playing 
the player played everything staccato, what is normal here (Germany) *g*
It may be nice to play just a little bit of staccato, but the program (capella 
then midi2ly) interpretated every note as note + spacer sequence.

for ex.: g''4*58/240 s4*2/240 fis4*58/240 s4*2/240 g4*58/240 s4*2/240

So the midi files are "corrupted", every note+spacer should be concatenated to 
a note.

I began to write a .sh utility to handle with the .ly file afterward, that is 
for J.S.Bach ok. It will be but very difficult using complicated rhythmvalues 
like c4..~\times 5/4{c16 d e f g}.

So it would be more accurate to purify/repair first the midi-file, then 
convert.

My question is actually:
-How do one repair (concatenate notes with this little staccato-rest) a 
midi-file.

I would have also a sed question, but later on, only if I dont have succes 
with the midi-way.

greetings from Francois
