Hi Heather,

For example the song Sunday Afternoon on my website was done using a Pan Flute on a PSR-500. Most GM sound systems make this a Flute, which does not have the breathy sound of a Pan Flute.
The beauty of the Kn7000 (and others) is that it is easy to substitute any native voice of the KN7000 or any imported voice for the GM flute voice. And of course with the superb sound editing capabilities of the KN7000, you can tweak the sound to rival the original acoustic pan flute.
The KN7000 provides tools that are beyond imagination. The only hard part is learning how to use them. I've had my KN7000 about a year now and the light is just starting to come on in my brain regarding some of the finer points of the keyboard.
I hope that I live long enough to figure most of it out.
Regards,
Walt
