As far as I can recall Cakewalk Pitch Shifter was a 32 bit DirectX plugin (which won't work in 64 bit Sonar / CbB).
The equivalent is Cakewalk Time/Pitch Stretch 2, but as far as I can tell it can't be automated.
For vocal pitch shifting, take a look at MAutoPitch by Melda Productions, which is free and can be automated.
