I own a wonderful S750 sampler, which is the centre of my musical world. It is fitted with the original processor. There was an upgrade processor developed. I've asked Roland ... they are now out of stock of the upgrade.
Is it worth getting one fitted? Does it make any real improvements to sound/time/usability?
Does anyone know where I could get hold of a processor ... are there any out there in the ether?

I still use the Roland original software for the unit.
Is there anything better available?

Does anyone out there have any skills in re-programming it?
... I have some real problems with a few of the ways it works & would love to be able to sort them out.

Thanks.
