Nardoni2002,
Sounds like what your asking is. Would you change the inversion of a particular chord if you were in another key? The answer would be no. Actually if you want to use a minamalist approach you only need to learn one chord postion. Ex. I play G in root postion. If I'm playing in the G scale, G is played in root position. If I'm playing in C, G is played in root position. In F, G is in root. Is that your question? Did I answer it?
I have to change position on my Yamaha PSR550 when I play for example a Dsus. Yamaha thinks its a G?? So I am forced to play in root postion, so it will be recognized correctly. Does this happen as well on the PSR2100?
