Main Configuration File
The
config.txt
configuration (stored in each bank) file is a simple text file to be
edited with windows notepad.
It is composed of 23 parameters that
must all
be present in the file (or then in the
override file, see furhter). Otherwise, the module will use default parameters for the
missing parameters.
The text file accepts comments on a stand alone line (not mixed with a parameter
line). The comment symbol is the C language double slash ‘//’ as the very first
characters of the line.
PC now also has another style of comments using the Emacs script syntax '##'.
To "comment" has 2 kinds of use. One is to disable a line like in the example below:
## switch=2
switch=1
The other use is to leave a comment or a note to remember something about the
configuration or the soundbank, like in this example.
## beware, ch1 drive should not exceed 900
color0=700,400,100
the double slash '//' comment is now reserved as the single comment exported to the
Real Time Configuration Editor (R.I.C.E.™). Use the // comment to name the
configuration to reflect its "theme" like:
// Bank1 - Novastar sound font
Certain parameters are integers, others are floating point numbers. Format must be
respected: even for a round value like ‘1’ for a floating point parameter, ‘1.0’ has to be
entered.
To modify the file, insert the SD card in the USB card reader, and then browse the
contents with windows file explorer (on
E:
for instance). Double-click on file
config.txt
: the notepad opens. You can directly save the file on the SD card. Once
the configuration is over, simply remove the card from the reader after having it
“ejected” (right click on the reader device in windows explorer, contextual menu,
eject). Put the card back in the saber and test you new setup!
The configuration file
MUST BE LESS than 1024 bytes
. If the size is bigger, the file
will be skipped without further analysis and defaults parameters will be used. The
basic configuration file is about 200 bytes, and 450 bytes for the override file, with a
few comment lines for an easier reading. Make sure not to add too many comments in
the file. If you are not sure of the file size, check it in Windows file Explorer, with a
right click on the file, then “properties” in the contextual menu.
Make sure you have no space characters at the beginning of the line, or
between the ‘=’ sign and the value of a parameter.
