XMIDI file format

Question

I am going to write a converter from Miles Sound System Extended MIDI to standard MIDI file, but I am unable to find any good documentation on this format. There is a DOS converter at http://www.hitsquad.com/smm/programs/xmi2mid/, but it is useless on 64-bit platforms and there aren't any sources of this program. There is also John Miles' website http://www.ke5fx.com/ where older AIL Version 2 is, but my C and assembly language capabilities aren't good enough to understand it. I have found a converter in Java at http://de.glibly.de/?site=software&lang=eng, but it has strange tempo issues and I haven't found a way to fix it yet. Could you point me to some documentation or a working converter with sources, preferably in C#?

Answer 1

The only completely working converter I've found so far is the in_midi.dll plugin of WinAmp.
