I have two questions about MIDI file exporting.
1 - Resulting file are often huge. Does Metro SE export compressed MIDI files?
2 - I imported a MIDI file into Metro SE (128 K, 121 measures, 9 tracks, type 1), deleted three empty tracks, then I exported to a Midi file again.
Metro generated an empty file! 344 bytes.
I saved all as a Metro file, closed it, reopened it, and exported it again. All worked fine, the file was 168 K.
Just for sake health, what was wrong?
