"Arvon,
I've played WAY more bad acoustic pianos than bad synths in my 30 year carreer."
What does this have to do with anything?
Of course there are bad pianos, and there are bad synths. But the worst accoustic piano will sound better than the best synth emulating a piano.
I would stop wasting time and either get:
a. a real piano
b. a sampler
c. a 5k$ electric piano with 6 sounds.
Synth's just don't do a good job of emulating real instruments. If you want to mimmick real instruments, get a sampler.
