natool is a sync tool for the venerable Neuros 2 digital audio computer. Its main use is to create the database the Neuros uses to store audio metadata (e.g. titles, artists, etc.) and which needs to be done on the host computer. Unlike the equivalent software included with the Neuros, natool is designed to run on Linux and other Unix-ish operating systems.
It's reasonably fast.
It does playlists.
It handles non-ASCII characters in filenames and tags somewhat gracefully. (They'll work but I can't guarantee they'll be readable.)
It can synchronize music folders directories between your computer
and Neuros just like
rsync but with a slightly better handle on the
wierdnesses of the Neuros' file system.
It's completely non-interactive and command-line driven. This means you can use it from scripts.
It doesn't try to "helpfully" fix your tags unless you ask it to.
Linux or another Unix-style operating system capable of mounting the Neuros.
Perl 5.8.x or later.
Class::Std and Test::More modules installed.
A Neuros with the hard-drive backpack and firmware version 2.28 or later. (Others may work but I've only tested it with 2.28.)
