Question on mixing and matching engines in a sound/bank

[mymusic42]

It's been a few years since I used an Oasys, but I seem to remember that you had to predefine the type of data that would be held in a certain bank (i.e. HD1 vs. EXi). Does that limitation still exist on the Kronos?

ON a related question, since any program can apparently consist of any 2 engines, does that mean that mean a program could consist of a an HD1 and an EXi?

Thanks
