Jonathan Scott said:I note that Roland claim that their latest top end pianos have "Sound Focus" technology. Now that I've experienced their sound without that technology, I think they need it.
That is a common problem with sample-based instruments, because there is no interaction between the samples for each note. The result is more like having 88 separate pianos each with one note, compared with one "real" piano.
A good demo of what is misisng is to silently press and hold down say the C below middle C and the octave below, then play a short loud middle C. On a real piano, you hear the resonance of the other undamped notes ringing on. On a digital piano - maybe, maybe not.
Another test is play and hold a big chord, then depress and release the sustain pedal a few times while holding the notes with your fingers. If you can't hear the resonance of the other strings kicking in and out, it isn't going to sound like a real acoustic piano.
I think "physical modelling" is the way to go over this. The technology isn't completely there yet, but give it another 10 years or so to develop...
This is a good example of where the technology has got to so far: http://www.pianoteq.com
It certainly passes the above tests correctly. It also includes things like the effect of the hammer impacting a string that is already vibrating, so repeated notes don't sound like machine gun fire, and (just like a real piano) you get occasional random "mis-hits" when playing trills etc.
