My example of natural/ simple expressive style of realistic guitar strums/ bass line.

Transitions from chord to chord on the Korg always felt rather 'lumpy' and it seemed easier for the Korg to get the wrong interpretation of a chord.
I believe someone mentioned before that coding language ( for styles) that Yamaha uses is different from Korg and Roland. That could be the reason for chord interpretation of timeliness.
