PC to mac convert: What's the method for accessing a mac's built-in GM sounds?

Cheers! There's also a prog for accessing / setting up a GM sound synth on a Mac, which works from Pd. It's called 'simplesynth'; version 1.1 is here: http://notahat.com/simplesynth

I'll just post below for the sake of info something that I learned on another forum:

"Macs do not have onboard GM synths. QuickTime used to have a GM softsynth but Apple pulled that feature a long time ago"
