Hi Nomad,
You need to download and run Grauws editor tool.
http://www.grauw.nl/projects/gaia-tool/Make sure the Gaia is switched on and the usb lead is connected to your computer.
Run Grauw's editor tool.
Then just copy and paste the patch Flute-01.gaia into the editor library.
Next, right click the patch and tell the editor to 'copy to temporary patch'
Hey presto the patch will installed on the Gaia. Save it into a temporary patch if you want to keep it.
Have fun, I'm not too sure that the Gaia is the best synth for orchestral sounds, but is certainly makes some nice pads.
