Jim, I love the song and the way you played it, thank you. ---more
As far as the comparison between keyboards--- My opinion – presuming you did not edit or adjust either keyboard---
Yamaha’s bass is too strong, a bit unnatural for that type of song. The G70 sounded even and natural.
The lead, the accordion was out front on the G70. On the Yamaha the lead seem to be at the same level as the style.
On my Tyros 2 I normally bring the style volume down somewhere between 85 and 90 so the melody stands our front.
