How do I reset SC-8850 via midi?

I have an SC-8850, and just as earlyer models, I have problem whith reseting all controllers. If I play some different songs, after a while it starts to sound like a Sound Blaster 16 soundcard...Then I have to reset it "by hand". After that it sounds normal again, but I get a BIT tired of doing this, since I play in a band. There must be a way to reset it via midi. Please help me, I'm getting desperat!
