Disklavier

From: "Robert Welcyng" <rwelcyng@...>

B: To preclude such a gross ambiguity, a different pattern, called the Gray
Code, is used on the mask. The relevant characteristic of the Gray Code
is that only one mask column (thus bit) changes during any row
transition; thus, ambiguities can be reduced to a single bit.

Hi Bob,

Thanks for the reply...

I have worked with several embedded designs in the past utilizing rotary
encoders which also use Gray Code coding. When Carol had mentioned 'using the
gray scale', I wasn't certain as to what she was referring to.

B: Now, everybody, please join me in shutting down your computers,
returning to your pianos, sitting down, and trying to learn to play
something on it--with your hands and fingers on the keys.

Will do. Speaking of which, I see that Yamaha is about to introduce a 'on-line'
library program currently titiled 'Digital Music Notebook' which looks
intriguing. Will this be, in part, for the Disklavier? In other words, will the
MIDI files be made to work with the DKVs?


Thanks,

Danny Simpson
