Finally, 6 months after announcement, Synthogy has put some demo's online, although the Yamaha is still missing.
Jugding from first impression I'd say it can compete with the other big piano samples around. So the sympathetic string resonance dsp they implemented seems to be working; they don't use sustain samples. That's good news: if the dsp works, the sustain pedal works more like an effect instead of a trigger for other samples.
They really need to put up some demo's without sustains though. Just single notes, unsustained, not too fast, not too short. I think that's the hardest thing to get to sound like the real thing.
So what do you think?
