Bitmap Window; Bitmap Window Data Format; Creating Bitmap Data - Yamaha VL70-m Owner's Manual

Bitmap Window

The VL70-m Bitmap Window function makes
it possible to display 16 x 16 dot icons and
simple animation sequences on the VL70-m
display in the PLAY mode. The bitmap data 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.

Bitmap Window Data Format

The format for message window data is as follows
(hexadecimal format):
F0 43 1n 4C 07 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 bitmap data consisting of a
string of 48 2-digit hexadecimal bytes.

Creating Bitmap Data

1. Block out the desired design on a 16 x 16
grid, as shown in the example below.

2. Filled squares will be represented by ones,
and empty squares by zeroes.

3. Divide the design horizontally into three
sections: two seven-columns and one two-
columns in width. Add one column of squares
the left of each section, and 5 columns to the
right of the 2-column section, as shown in
the example below. You now have 48 rows,
each 8 columns in width.

4. Use the chart below to convert the ones and
zeroes in each row from binary format to
hexadecimal format. The "bits" in columns 0
through 3 become the first digit, and the bits
in columns 4 through 7 become the second
digit of each hexadecimal byte.
For example, the 11th row in the example
forms the binary byte:" "01000011". Columns 0
through 3 form "0100", which, using the chart,
becomes hexadecimal digit "4". Columns 4
through 7 form "0011", which, using the chart,
becomes hexadecimal digit "3". The 11th row
in the design can therefore be represented by
hexadecimal byte "43".
