A Simple Example From The File
As a simple example let's look at the MUTE_METHOD option. Scroll
through the Options Text File (or look at the sample file listing at the end of
this Appendix) until you see the following three lines of code:
// Syntax: MUTE_METHOD:?
// ? 0 (default) = ON button, 1 = ON AIR.
MUTE_METHOD:0
The first line describes the syntax for this option. It starts with two slashes,
which are interpreted as the start of a comment line. Comment lines are made
for us to read, and the surface CPU ignores them. This line shows that the
syntax for the option is the keyword MUTE_METHOD followed by
a colon (:) followed by some character, as represented by the '?' character.
The next line indicates that the '?' can be replaced by a '0' (a zero, not the
letter O) if a muting channel being ON will trigger the mute, or a '1' if the
muting channel must be both ON and assigned to a main bus (thus making it
ON AIR) before it will trigger the mute. This specific example shows that the
default setting is '0' for this option. Please note that this may or may not be the
case for your particular surface, as the default option is subject to change.
The idea of how to use the file remains true.
The third line is not a comment; this is the line the surface CPU actually
reads from the file. This line, as shown, sets the muting method to ON (channel
must be ON to activate a mute, but need not be ON AIR). If this is not the
desired operation, this line must be edited. Change the '0' to a '1' and the muting
method will change so that a channel is required to be ON AIR before it will
activate a mute. As indicated in the instructions above for modifying the file,
the actual change to operation will not happen until the surface has been
rebooted and has read the modified file.
The edited line must follow the established syntax precisely or the surface
may not behave as expected.
