Scott...great posting! Thanks for taking the time and interest. I'm not used to getting that kind of info from other musicians. Although I live in the NYC area, no one here is much interested in the type of thing you're talking about and if they are, they're not interested in taking the time to "reveal" trade secrets. I'm like you, I try to help whenever I could.
You are absolutely right about what you wrote. I should spend more time "listening" and "emulating" rather than finger practicing. I'm in the process of buying a new arranger keyboard so I'm actually going to do both: read the books and spend more time playing with each instrument. I've taken everything you wrote and put it in a single text file to review.
I'm a seasoned professional myself many years now. May I ask what is that keyboard in the photograph, or what instruments are you now using in your setup? And, what part are of the country are you in?
