if you are sending data to the application bus on a mac then you need  
some sort of software synth to play the data you send. there is a  
nice, easy to use, free synth called SimpleSynth developed by Pete  
Yandell here:

http://notahat.com/simplesynth

(it looks like he is working on it again, there is a new release!)

for real time midi from Grace do this:

1. start simple synth and select the application bus from its "midi  
source" menu
2. start Grace and select Application Bus for Midi Output.
3. try some of the examples in doc/scheme.html, both scheme and SAL  
should work in realtime. You can configure the midi port for  
microtonal output and sending specific program changes to you  
software synth, all this is under the MidiOut menu.
