Did you ever find a player? I found this solution, so I thought it might be nice to put my findings here for anyone else looking for it.

I read through the thread ref'd by thedead1440, and I found that the/a wildmidi package is in the harmattan dev repository (http://harmattan-dev.nokia.com harmattan/sdk/free Packages) and could be installed with "apt-get wildmidi". However, I have not found a freepats package, so without instrument patches wildmidi works -- silently.

So I located the freepats website: http://freepats.zenvoid.org/ and download and extracted it (http://freepats.zenvoid.org/freepats-20060219.tar.bz2 or http://freepats.zenvoid.org/freepats-20060219.zip). Then Copy or link it to /usr/share/midi/freepats/ which is the default patch directory in /etc/wildmidi/wildmidi.cfg.

Now wildmidi plays midi files and sounds pretty good.

Sorry if there are typos in any of these links, I retyped some of them . . .
