Doc,

It seems that the only difference between the DGX-620 and DGX-520 (aka YPG-525) is that the latter has unweighted keys similar to those on the DGX-305. Please double check this with George Kaye or some other dealer as Ijaven't touched a DGX-520.

The 520 is also less expensive so it should be closer to your budget limit.

As far as registrations are concerned, You have registrations banks on your DGX. There are 2 memory banks with 8 cell each where you can store your keyboard settings like style, voice, dual split etc. Please refer to page 68 of the DGX-305/505 manua. It is all explained there.

The trouble is that with the DGX-305 you are limited to a total of only 16 registrations. In other words you are limited to 16 songs set-ups.

On the other hand, as far as I understood from G. Kaye's words, with a DGX-620 or 520 one can load those registrations from a USB pen drive.

The new 620 and 520, like the 305, can load only one external style at a time. Since those keyboards use USB as a storage media there should be less loading time. Please ask a 620 user to verify this.

I am sorry that I cannot provide you with more specific information but my experience with the 620 was only 30 minutes and I wasn't interested in trying out all aspects of its functionality.

Regards,

George
