General Midi Question, Old PC guy new to MAC Options

[thunderstick]

First of all, I want to appologize to everyone with regards to my ignorance to Macs. I only just started using them and it is all greek to me..<laugh>

I am using Pro Tools LE 6.2 and a G4 Mac.

I am importing a MIDI file and want to play it in Pro Tools but the catch is that I do not have any outboard MIDI devices. In the PC world, the general midi takes over and you hear the tracks.
In Pro Tools, nothing. QT plays them fine but nothing in Pro Tools.

What do I need to do to get Pro Tools to use the internal Mac GM sounds to play in the software???

Please help, it is driving me crazy.

Thanks,

Ian
