On second thought, are you using the QY as a sound source and it'ss not changing patches when you change songs? If so, you need to reset to GM/XG before each song - at least that what it sounds like to me. That was one of the problems I experienced with the 100. If you say you had no problem with the 100 but do have it with the 700 maybe you just need to find that page in the edit section. Again, good luck. If this is what you're doing - and I may be completely wrong in my assumption - then Band In A Box (BIAB) can do this as software and the resulting file can be played thru any GM/GX sound source.
