I was wondering is it possible to run 2 different power supplies within the one effect pedal. With one supply being
+15V -15V from a 9VDC source through a charge pump. With the second power requirement for a second part of the circuit isolated from first part also powered from same 9VDC source, only this section powered as +9v and 0V GND with bias for op amps.??? If this is possible, I were hoping some kind people here could please advise me on how to achieve as much, even a pictorial basic circuit design to show how, any advice greatly appreciated. Thank you.

Depends on what you mean by "isolated".
But if this second part is also op-amp based why not use the bipolar supply there as well? We'd be more able to help if you tell us the specifics.
