But the voice architecture, and effects etc. seem very Triton-like, to me. There doesn't seem to be much from the M3 in the PA2X, that's for sure!

What (apart from some marketing-speak) exactly is different between the voice architectures of the Triton Extreme and the PA2X?

More oscillators per note? More velocity layers per note? More filter choices?

Bottom line is, even if there ARE (and I await you telling me), do they actually USE them, much. I certainly seem to HEAR a Triton when I hear a PA2...

The only different thing seems to be DNC, and just like Yamaha, that seems to be an arranger only feature so far, until it gets rolled into a new WS (does the Kronos have DNC? The M3 doesn't AFAIK). And it still is only as good as the samples that it is set up specifically for.

Possibly the engine might have changed, but from listening to M3 presets, and having heard a PA2X, very little in the way of the sounds themselves got ported over, IMO.
