Re: [Freecycle-users] Corrupt midi output file

[Predrag Viceic]

Hi Marco,

Sorry for not responding earlier.

I recall having problems with opening of midi files in newer versions of MuSE, 
Rosegarden etc.  This was, if I remember well, related to differences between 
different revisions of the SMF standard. I'll look at your comments about 
MThd and add it when I find some spare time.

If you have some programming knowledge you could look at:

http://cvs.savannah.gnu.org/viewvc/freecycle/src/midimanager.cpp?revision=1.4&root=freecycle&view=markup&pathrev=MAINTENANCE_0_6_ALPHA

Dont checkout the last revision but use MAINTENANCE_0_6_ALPHA cvs tag.

Regards,
Predrag
