comparing acoustic grand piano tune to digital piano tune

[robson]

recently I've got my baby grand tuned the very first time and out of curiosity I have compared tune accuracy to my digital piano. It sounds to me the acoustic "swims" a little bit more then DP, especially audible with octaves. Is it normal? Also when tried software tune application DP was more accurate with pick frequency. Playing normal, chords etc though acoustic sounded more vivid and full and the effect is gone. Is it normal?

A dp will always be more accurate in sound reproduction. An acoustic on a daily bases, ever so slightly, loose their tuning thru the tension and expansion of the strings to which dp's don't deal with. Also the ear and method used matters too...

Your acoustic may have been more stretch tuned than your DP. Upper end DPs these days allow you to play around with the amount of stretch, so you may be able to get closer to em being the same.
