Yes. Sorry.

Yes. I was sucessfull to loop a midi file with Jack and Rosegarden. The
outputs was routed through mididings and went back to Rg for a new
record on a new track. But it was not for this purpose and i didn't look
for the meta information.
But for now, if i have a copy about these informations may be i can try
again this experience? It isn't a piece of music, only a succession of
drums patterns. I can organize them to avoid different time signature...

I haven't check out yet.

No. Like i have said these are drums patterns written by Lilypond. After
the famous transformation i could join all the tracks in one if i want.
