The Message Window; Message Window Data Format - Yamaha VL70-m Owner's Manual

The Message Window

The VL70-m Message Window function makes
it possible to display text messages up to 32
characters in length on the VL70-m display in the
PLAY mode. The messages can be transmitted in
the form of a data string from an external MIDI
device, and will appear on the VL70-m display for
about 3 seconds. A message could be placed at the
beginning of a song data file, for example, so that
the title of the song and other information appears
on the display at the beginning of the song.

Message Window Data Format

The format for message window data is as follows
(hexadecimal format):
F0 43 1n 4C 06 00 00 xx xx .... xx xx F7
"n" is the device number minus one. If the VL70-
m device number is set to "1", for example, "n"
should be "0".
"xx xx .... xx xx" is the text data. Each character is
represented by a single ASCII -code byte (2
hexadecimal digits). Refer to the chart below for
the ASCII code for each displayable character. The
numbers in the top row are the first digit and the
numbers in the leftmost column are the second
digit in the byte representing each character. The
capital letter "A", for example, is represented by
hexadecimal byte "41".
