Right so the nearest I'm getting right now is by using Bank 0 Prog 1 with a few tweaks (dial envelope depth back to 2, note off level to 1, attack to 3, decay 8, dynamics 3, cutoff 6, resonance 2 and balance 2) and then using an mxr bass preamp later in the chain with a bass boost and mid cut to fatten the whole thing up. It's far from perfect but its at least useable in the mix with the band. I also use the same setting for Lets Groove by Earth Wind and Fire which really shows it's not quite the 80s sound I have been chasing. I'll keep looking and if anyone finds a way then let me know!
