So this is a sample of a sampled piano Kawai Concert Grand Ex (2m78 long please!), There are more than a simulation of resonance of the strings and trunk ...

The Samples range from 46mb to 95MB ... there's plenty to do
Perhaps a bit heavy for live anyway ..

SOUND QUALITY

There is impressive, I'd say I've ever seen a better piano sound with respect to the bass and middles ... the highs are just screaming for my taste (compared to the piano sounds in kurwzeil example)
The quality of mark-resonance is very good too, with the sustain pedal we believe it.

So outstanding sound quality 1000fois better than the sound of the tritone in any case

OVERALL OPINION

A very good impression, then, the sound is good ..
Just a pity that the treble is as hard and crying.

A great product that still is not cheap, but cheaper than the other and probably better bill.
I am very happy with my purchase
