Lookup SoundNote and EmitSound - the spec seems quite straightforward. 
There should be no need to learn J/Link or MathLink to generate MIDI 
sound with version 6, though this was the only way to do it in earlier 

J/Link is probably easier to use than MathLink because you can start 
with examples that are written purely in Mathematica code and call the 
Java API (i.e. you don't need to write any Java code).
