Uncle Dave
I went from playing organ to full sized accordion, it took
some getting used to.
Then sold every thing, later on got a MID sized accordion
for a little bit of nothing just to keep up with playing music,
talk about a change in size of key's !!!!!!!!!!!
But I made the grade, played that little thing for years,
then went to Technics KN5000 no problem, then went to the
9000 Pro still no problem.
I'm not as good as you, but I can't blame it on
the size of the key's.
Good luck with your search.
Maybe the Korg PAX-1 will be the one, let us know.
