How can I play a midi file?

[Chris Gilland Desktop]

I'm curious how in Tiger you need to go about playing a midi file with a 
.mid extention.  I hear quicktime'll do it, but, you have to supposively 
first, convert it to a movie file.  That's way more complicated than I wanna 
deal with.  I just want a simple player that is freeware.  Even better, 
would be open source.  I'm sure things like Garage Band would do it, but 
frankly?  I really! don't wanna pay $79 just for the thing for openning 
mids.  Granted, for recording, in general, I am considerring it, but, not 
sure as of yet.

Quite honestly, I really wanna try this trial that I downloaded.
Anyway, for just a simple player that I could have so I can command o on the 
file from the finder, and it start playing, would really be extremely nice.
