Is that at the heart of your argument?
Well, I have given many times what the heart of my ideas are. Some of it is not easy to put into words, as it actually probably should be the case, since, if I could sum up everything I intend to do at the piano in words (or in a painting, or what have you), there would be no reason to go to the piano.
We could go 'round and 'round about this, but the only reason I am sitting here at the precise moment is because I am tired/sleepy and procrastinating other things. At the end of the day, what matters to me, is that my current concept of music and the piano does not lead me to the computer as a means of expressing myself musically (at least not in the same way as it does Machine-Kevin). Different people have different concepts, so I am not even anymore trying to argue what is good/best, so on and so forth. It's just not *my* concept, and I don't need you to understand the ins and outs of why that is.
I get it, times, they are changin'. There are new tools available to us that we did not have before and yes, that does create new expressive possibilities. In some sense, that is always the case (for example, prepared pianos to get new sounds). People often like to equate 'new' with 'better' (which is, of course, not always the case in any field), and often times in the process of trying to break through the "market" (whatever that is, exactly), will put down the "old" in order to justify the new. Yawn.
One interesting point has come up for me in my own private thoughts though. Just yesterday, as a matter of fact. I was pondering the advancement of technology, the fact that Haydn's music, for one example, was not necessarily written with the modern day piano in mind. Similarly with JS Bach's music, for another example. Different people feel different things about that, and some individuals do even go so far as to play only period instruments for the corresponding music. Interestingly, I had the opportunity a few years ago to talk with an individual whom has chosen to concertize on a pianoforte, and I asked him why he chose to do that when he had been raised on a modern day piano. I loved his answer. He said (to paraphrase), "at some point, his concept of the music just demanded it." I think that is very interesting. At this point, my concept does not demand that, but who knows, maybe at some point it will ?
Anyway, what actually struck me as I pondered all of this stuff was whether or not playing a Bach work, say, the Goldberg variations (which I once saw a woman perform the complete set TWICE in one concert, first half on modern day piano, second half on harpsichord (btw, one of the most truly fascinating and outstanding concerts I have ever been to)), on a period instrument vs. a modern instrument, actually makes the music itself any more or less
musical ?
ha ha ... suddenly I am finding that I could go on and on and on about all of this. Don't worry, I won't

. Bye !
[edit] I realized that I am not sitting here ONLY because I am tired and sleepy and procrastinating. It's actually the regular old reason : I love music and piano !!
