HI Craig, I don't have any help for you at this time.
I am still trying to get a working driver for midi and the voice editor

Hi Bert, I have done the registry hacks you advised but it did not resolve the problem. I have sent you and email with the registry entries I see there and maybe you have further advise. I keep getting the motherboard sound card driver as the default device instead of the yamaha USB midi driver. Not sure what to do about this.
Thanks,
Bebop
