Hi Peter

Yes, it will work on your PSR3000 just as it does on my Tyros, BUT:

Not all sounds will transfer sounding properly, but you can easily keep the ones that sound good and substitute your own favorite sounds from your particular keyboard.

You will easily be able to tell which voices sound good and the ones that don't. The ones that don't sound good kind of drop out in volume, at least that's what happens on my Tyros.
