YOU never know what I'll do Ian...but I know one thing ....what ever I play will sound great somehow some way as I look back in my picture albums It's amazing how many different Kb's I have performed with thru the years, but the music is successful always.
Well, Donny, you sure made that KMA sound pretty darn good (I haven't heard better), and I'm sure you could do the same with any instrument.
However, I just can't imagine you with a Tyros4. Maybe a Korg PA-3X? You like the Korg sound, styles, and OS.
