XMF Patch Type Prefix Meta Event

rp32 XMF Patch Prefix Meta Event.pdf
XMF Type 0 and Type 1 files contain Standard MIDI Files (SMF). Each SMF Track in such XMF files may be designated to use either standard General MIDI 1 or General MIDI 2 instruments supplied by the player, or custom DLS instruments supplied via the XMF file. This document defines a new SMF Meta-Event to be used for this purpose.
