tuxguitar-oss is a plugin for TuxGuitar. It connects TuxGuitar’s MIDI sound output to OSS (Open Sound System), one of the most popular sound output systems for Linux, FreeBSD and other *nix operating systems. That means that with this plugin TuxGuitar will no longer use Java soundbank, but OSS MIDI output.
There isn’t any official tuxguitar-oss prebuilded package available. You should build from sources before install it.
To install the plugin, you must copy tuxguitar-oss.jar into $TUXGUITAR_HOME\share\plugins
