Thanks for your feedback.
In this forum and other places, I have been inquiring for a lot of keyboards types, because I have been composing on a small midi 5 octave, and is very limited. Now, I can't make my mind between going digital or for the 'real thing'. The problem with synths, is that you cannot upgrade them (or just for the time the company will support you), so they go obsolete. A real piano will stay a real piano for over the time...but out of tune pianos are horrible, rarely I have played a piano in perfect pitch, indeed. Anyone of you have personal experience on tuning, for a short or long time?. I'm waiting for more opinion of players who had tried this.
