Great demos ..but I don't get a sense of the piano sustain 'bloom' that you can get on a real piano. At least on my Bechstein at home the sustain is amazing. I would like to hear some more creative pedalling and some louder passages with the soft pedal. Many pianists ignore the louder tone of the soft pedal which is very expressive.
No matter what the demos sound like I'll never know if this piano works for me or not until I try it for a few hours. I'm hoping this will be the last sampled piano I'll have to buy for a long time.
