I've just spent several hours to play IVORY in a music store :
First, they said "real sympatic resonance". the sustain effect sound more like a synthetic reverb
than a pedal down convolution.
they are no overtones and no release overtones.
so the word "real" is not right.
The CPU meter is good but it eat a lot of memory (more than 1 GB). The DFD doesn't work correctly
when you have more than 24 / 160 voices. (on a separate external 7200 HD USB2)
You have to have a fast HD
the CPU performance is very good but it's eat memory again.
You hear the safe voices (strange phase effect).
The Bosendorfer is warm and indredible. It's one of the best Bosendorfer out here.
It sound better than the official mp3 demos
The Yamaha C7 doesn't sound full and right, and the Steinway sound synthetic between mf and FFF layers.
If you want a good Yamaha, go for TBO or Vintaudio Yamaha C7
Only the PPP sound right on the Steinway. But the colour between layers are strange.
(i've to adjust some settings)
the built effect sound like classical reverb, and haven't the same quality than the CONVOLUTION
of Akoustik PIANO.
Ivory for the Bosendorfer only.
Akoustik Piano Steinway D sound Warmer and better than Ivory german D Steinway.
