Getting MIDI working in Slackware isn't as easy as it should be. Here's a simple solution.
I've tested it on a full install of Slackware 13 that had no installed packages other than what came with the CD.
1. Download the SlackBuild
Untar it. You now have a build directory called “TiMidity++_SlackBuild”.
Download the Sources
The following files go in the TiMidity++_SlackBuild directory:
2. Run the SlackBuild script
Go to the SlackBuild directory. As root:
chmod +x TiMidity++.SlackBuild
3. Install the Package
When the SlackBuild script finishes, you'll have a TiMidity++ package in /tmp. Use installpkg to install it.
4. Add TiMidity++ To Your Boot-Up Sequence
Create a rc.local file in /etc/rc.d and set it as executable if you haven't done so already. To this file add the line:
5. Enjoy MIDI
You now have a MIDI port 128:0.
You can also play MIDI files with TiMidity directly. This allows you to use Mozplugger to play streaming MIDI files in Firefox.
Very special thanks to Phonon and Daedra for their contributions.
