Change Screen Properties
Screen properties are changed by using the 'Set Screen Properties' command ID. The property
can be either text, a color, or a value. Colours can be specified using indices from the colour table
or using RGB values.
The general format of a change property message is as follows:
0xf0 0x00 0x20 0x29 0x02
0x0a 0x01
Set Screen Properties Command
The column index for the value:
0x00 (0) to 0x07 (7) - Columns 1-8
0x08 (8) - Centre screen
0x01 (1) – Text
0x02 (2) - Colour
0x03 (3) - Value
0x04 (4) - RGB Color
The index of the object to change. This is specific
to the layout. See the layout details for the
values.
Depending the type of the property:
Type 'Text': String of 7-bit ASCII characters,
followed by a null (0x00) termination.
Type 'Colour': Index into the colour table (0-127)
Type 'Value': The value to set (0-127)
Type 'RGB Color': Three bytes ( e a c h 0-127)
indicating the red, green and blue colour
components separately
Note that multiple properties can be sent in a single SysEx message by repeating everything from
the column index to the data. This has the added benefit that all of the updates will take place
simultaneously.
