I guess Deluxe Music doesn't support export to Type 0 or 1 MIDI files.

MIDI itself isn't going away anytime soon. Its transport medium agnostic, so it merely migrated away from 32kbps serial to faster mediums like USB, Firewire, and Ethernet. That and MIDI sees application outside of music making, its a popular way of transporting time code. Heck, it even runs the IR remote control for my Creative sound card (via sysex I presume).
