How can I use SysEx request files?
Simply put them to the matching directory, which can be defined via the preferences, and the file will appear in the request popup menu. Some request files are installed in $KDEPREFIX/share/apps/sysexxer/requests. If your request file works, please send it to Christoph Eckert so it can be offered on the homepage. • How can I make my MIDI in- and output workee?
