What was I doing wrong here?
Hi,
I'm pretty sure that KMid and aplaymidi are both just simple players
that direct MIDI output to your soundcard's MIDI interface. (Someone
correct me if I'm wrong.) They are not midi _synthesizers_, so you
won't hear any sound unless you have a synthesizer attached to your
soundcard.
Instead, try Timidity++, which is probably in your distribution.
