Ha Don,
If only Onacimus would put his hands on those they would turn out incredible. I'm not that deep into style modifications & yes, Mega Enhancer can only do so much. But it mostly depends on the initial raw conversion from one brand to another. Of all, Roland styles convert best. Yamaha worst. Korg somewhere in the middle.
In any case, I tried my friend... Half a Merc is better than no Merc at all!
Cheers,
Henni
