Just curious, but have you tried any new Roland's, Lucky? (not that there ARE any 'new' MOTL and TOTL Roland's, but you know what I mean )

They play those legacy Roland styles pretty much as is, and have absolutely the BEST tools onboard to allow you to migrate them to newer sounds with the least fuss... E60 for lightness, G70 for the harmonizer, etc. (seems you want a 76)...

Some very nice condition used ones floating around (my backup I just bought looks like showroom).

An OS you are familiar with, great new drumkits and pianos, organs, saxes, etc.. True four Var, six Fill operation, Markers for live SMF restructuring, great harmonizer (on G70), and the great Cover and Makeup Tools you hear me brag about all the time...

Maybe the G70 is too heavy, but it seems to me a nice used E60 might fit the bill, save you a chunk of money, and at least allow you to continue using your styles of choice through a better sound set....

The devil you know, and all that....
