linthesia — Fork of Synthesia to GNU/Linux.
Linthesia is not currently distributed with MIDI files. Meanwhile, you can use your own midi files with Linthesia.
This manual page was written for the Debian distribution because the original program does not have a manual page. Instead, it has documentation in the GNU info(1) format; see below.
