Here's the Yamaha Montage TX816 Epiano. Listen to how magnificent it is!
It's 8 layers, each 16 voice 6-op, each detuned, panned, or changed in a different way in the operators. You can browse those patches easily and have heavenly sound.
There's no reason not to have such implementation in Plogue OPS7 - at least as an option. It's a world of amazing sound which was used only in the top productions.
