No - unfortunately they are not the same. The Manufacturer IDs in my version of <mmreg.h> range from value 1 (Microsoft) to 266 (Algovision). Apart from that, I develop this MIDI-driver (IEEE P1639 midi over ethernet) "just for fun", so I wouldn't be willing to pay $200 per year to get a manufacturer-id from the MIDI-association. Thanks for you response anyway.
