GM, XG, GS, GM2: all these standards carry the same arrangement, but your instrument does not read them the same way. Pick your model to find out which one to choose, how to load the file and what to adjust next.
That is not a problem: every keyboard, arranger, module and software reads General MIDI. The GM version of our files works everywhere. The guides above are there to get the best out of a specific model, not to make it compatible.
