Thanks Scook, unfortunately not. As my MIDI controller is an Edirol PCR as opposed to the later Cakewalk A-PRO.
I guess a different way of approaching this problem I have is:-
A:Find the location of the Control Surface profile files.
B: Obtain a copy of the the PCR-300 control surface profile file and insert it in the correct location so that I can select in Sonar.
Although why all the previously available control surface options should go missing on a rebuild is beyond me at this point. The only difference is that I have installed Cambridge build which was released over the duration of me rebuilding my DAW...
Any takers? I am so frustrated at not being able to use get my PCR-500 back up and running as a control surface.
