To modify a scorefile within pd, click on the [rtcmix~] object in a locked (i.e. editing off) pd patcher. This will open an editor on the current [rtcmix~] script. If the script has not been loaded with an [open] message, [rtcmix~] will create a temporary file for editing. BE CERTAIN TO SAVE THIS using the [save]/[saveas] message before exiting pd, or the work will be lost.
The [rtcmix~] here comes configured to use the popular "Notepad++" editor (https://notepad-plus-plus.org/). The configuration assumes that the editor is stored in the default location "C:\Program Files\Notepad++\notepad++.exe".
You can use an alternative editor and set [rtcmix~] to invoke it using the [editor] message. The [editor] message takes one argument: the pathname to the editor program. This pathname has to be specified using unix-like directory separators. For example, an editor located at "C:\Program Files\thebest\editor.exe" would be set by sending the message:
[editor C:/Program\ Files/thebest/editor.exe]to an [rtcmix~] object (note the escape (\ ) of the space in the pathname, too). Sending this message to a single [rtcmix~] object will set it as the default for all [rtcmix~] objects in a given pd session. The message will need to be resent if pd is restarted.
You can also use an external editor to create [rtcmix~] scorefiles. However,
be sure that any alternative editors you use can write "unix" or "OSX" line
endings, not Windows line endings (Notepad++ can do this, but
the plain Notepad that comes with Windows cannot). Native Windows
text files use a combination carriage-return/line-feed
scheme that will cause the RTcmix parser to crash. I haven't been
able to fix this yet.
