What is my Exclusive Message in my SX900 keyboard?

[juketsu]

Hi!

Could you please help me? I asked an acquaintance of mine to make me a midifile of a song. One whose pitch I can transpose, and whose instrument sounds I can turn on or off and play a part myself if I want. He promised to do it, but said he needs an Exclusive Message from my keyboard for everything to work properly. How can I find that Exclusive Message? My player is an SX900. I couldn't find it in the user manual, and I couldn't find it in the menus of my keyboard either. I did find the document SX900 Data List online, which has almost 6 pages of text about the Exclusive Message. Too much, and when I don't really know what I'm looking for. At least I think the Exclusive Message code is the same for all SX900 players... What is that code?

Best wishes,

Juke
