No sorry, I didn't say that, exactly.... But I can see how this line ..."Unless you are using actual mega voice patches..." could be perhaps a little confusing, I should have added ..."on the ES/XS".
To clarify further..the racks (ES/XS) have the mega voices but they are patched in a different way, (not nomenclature but in 0,32 terms), to how they are in the Yamaha styles, so a re-mapping is needed within the style.
Oh and the other thing is don't expect the full range of mega-voice guitars on the racks. There really isn't too many at all.
The presets have superb guitars, which in my view are better, but again you do need to do some re-mapping work within the styles you are using with OMB. It might have been me, but these preset guitars on the racks also seemed to have slightly different velocity trigger levels, so I also had to edit note velocities within the chosen Yamaha style if I wanted to use preset guitars.
In the end I just resigned myself to using non-mega guitars and basses as I really did not have the time, at that time, to spend on it. I was playing in a duo, a band, and some solo work, PLUS I had a part time "day-job" too, so I was a little busy.
