Arranger play is timing CRITICAL. If you have to stay with just a GM/GS engine to be able to be responsive, where's the advantage for an arranger player? It's cool for the studio, but how do you gig one without some serious compromise?

Maybe multiple CPU running in tandem might get us there, but until all the promise is realized in a realtime/hardware-like fashion, gotta pass............
