Hi Slyman, thanks for the heads up on using the A-PRO, I am sure it is a slight increase in quality with the PCR, which does not have touch sensitive pads, however, I have a Korg PadKontrol which covers that for me. I never swung for one because the PCR still does it for me, although I have been looking this afternoon at regional dealers who might have one in stock if I need to replace quickly.
STOP PRESS !
However - in the last few minutes I have managed to get the old Edirol Win 8.1 driver and the PCR working on my Windows 10 Professional 64-bit system once again ! The difference this time, was finding out how to access hidden troubleshoot options on Win 10 anniversary edition via a <cntr> restart...once I could do this, I could disable driver verification, amend the install batch file from 8.1 to 10 and.....well my PCR lives to tell the tale once again, despite being stranded at 8.1 by Roland....
If anyone else drops by this thread in the future - this was the link that cracked it for me.

Hope this helps anyone else...
