Re: [LAU] Rosegarden -> lilypond help

Greetings everybody, midi folks in particular; I have a .mid file that plays using the wrong instruments because it was composed before GM. Sent to the built in synth in an audigy2, it plays at normal speed but wrong instruments. Loaded into rosegarden (to fix this), it plays at about 1/100th speed. This doesn't surprise me too much as the originating program dates to 1991 on a TRS-80 Color Computer 3& GM was something we only got in the then brand new Sound Canvas's and such. Obviously something in the header doesn't meet .mid file specs. I did change the internal name from .ume to .mid in a hex editor, and reloaded but other than the track title now showing the correct string, no other effect. In an effort to see what might be wrong, I fired up the print preview which uses lilypond to generate the 'sheet' music. But from the looks of it, its going to use 80% of all 4 cores of this phenom for several hours to render, probably because of this same time error, (transport says its like nearly 3 hours long, but its a bit over 3 mins in actual play time) so the generated pdf is likely to be 40Gb! Does anyone know enough about this to tell me where, in rosegarden, to fix this? Or do I need the hex editor again? Or, heaven forbid, its a bug in rosegarden (shudder). Thanks midi folks. Cheers, Gene
