Exporting MIDI in C6?


I seem to be having a strange problem that I’ve never had before with exporting MIDI.

I have an arrangement of about 30 tracks or so, but whenever I export the MIDI file, it generates a file that seems to have errors in it (Sibelius reports a corrupted file), and when I look at it in Cubase, it’s only exported the first 13 tracks.

I’ve played around with reassigning channel numbers, reimporting tracks from XML, obviously I’m exporting a Type 1 MIDI file rather than a type 0, and I’m not exporting any inspector/insert/send data with it… so it should be a straight forward export process. I’ve done this hundreds of times before with C5, but I can’t seem to get it working in C6?

Anyone else experiencing similar issues? Is this a bug?
