back story: I got roped into playing a very short recital for a group of folks. Nice people, somewhat knowledgeable, and I want to do well for them. The music isn't a problem -- three Chopin nocturnes and a couple of Schubert impromptus, and some pop stuff as leavening and encores (if I don't get hooked first...). The problem is an odd one.
I'm used to playing a Steinway grand. I have unusually long fingers. The piano I will be using is a very nice Kawai digital, very late model -- practically new, top of the line. The panel in back of the keys has enough push buttons and widgets on it to do justice to a Boeing. Some of these turn on and off assorted accompanying drum tracks -- samba, tango, and I'm not sure what all else. These push buttons are, I find, close enough to the keys and sensitive enough so that the tips of my fingers -- particularly left hand -- brush them once in a while. Enough to turn them on...
Is there any way to disable the lot of them, so I don't get a nice drum section popping up in the middle of a nice nocturne? The owner of the piano doesn't know.
