Fran,

You'll need to unzip the SGM180 font and place it in the folder of your choice ( It inflates to approx 180 mb ). You will then need to open it up in a soundfont compatible sampler or app, or as the soundfont for a Soundblaster card if you have one of those.

If you don't have a soundfont capable app, here is the link to one that you can use ( it's freeware too btw ): http://www.rgcaudio.com/sfz.htm

SFZ will open up as a VST plugin in your favorite host. Then you simply identify the folder where your SGM180 and other soundfonts are kept, and load them into SFZ from there.
