Thanks for the reply. I thought this forum seldom gets any replies.
What I particularly didn't like in the Ultimate Piano CD's are two things:
1) Very short decay of samples (even at 96 MB samples). When I press a key and hold the sustain pedal, tones fade very quickly. The ROLAND acoustic pianos have longer sustains.
2) The dynamic volume range in velocity/touch response is small. Thus, when I play in pianisimmo, I feel like I am still playing in mp. Thus, I felt I could not be as expressive. The range is more like from mp to ff and yet, the corresponding attack/volume I get in response to how hard I hit the keys do not match.
Does this mean I need to do some tweaking? I thought that if I bought a CD-ROM version, all I need to do is load-and-play?
