The sound on this piano is incredible. Korg truly did sample stretched tuning and string resonance. You can also choose among 9 temperament types and 5 touch sensitivities. I’ve played many synths and pianos over the decades - if it weren’t for the plastic keys (which are excellent quality), I’d honestly think I was playing a baby grand. I’ve never felt that before in this price range.
Assembly was quick and painless although indeed, the keyboard is very heavy. Korg fit everything seamlessly, you can tell a great deal of engineering went into it.
Overall delighted with this digital piano.
