Rikki, Glad to help anyway that I can. Thanks to Domenik's post above, I realize the error I made in forgetting that 4 of the arranger tracks (9,10,11 and 12) have been designed for drums and percussion and as such they do not follow chord changes. This would make them unsuitable for other accompaniment instruments. So that would leave us with 12 such tracks and not 15. altering the number of unique accompaniment instruments per variation (not used in other variations) to 4 instead of 5. Hope I didn't cause too much confusion with my answer.

For someone with your experience in tweaking or remapping styles with OMB and using soundfonts, Using the Mediastation should be a "piece of cake". With the giga sound library already connected as the soundsource all you have to do is make sure that the music data is in the form of std midi files and that the style parts have names that the arranger engine can recognize. Names like intro1.mid, intro2.mid for introductions or like var1_maj.mid, var1_min.mid for variation 1 major chord accompaniment and variation 1 minor chord accompaniment, respectively and so on.

And with onboard tools already installed like Rosegarden, Ardour GTK, Audacity and others you can do almost everything from inside the Mediastation. And these programs are updated to the most current version with the Mediastation OS upgrades. I received the newer version of Rosegarden about 4 weeks ago automatically when I loaded an Mediastation OS upgrade the iso installer handles it with no action necessary on my part.
