There must be a way.

Hey dude... logic stereo plug in tab selection special, leads to choices of detune or pitch enhance. Im not sure if that is what you need. let me know.

Hey James
not sure if this will help, but if you want to just raise or lower the pitch, the pitch shifter plug in in the channel strip (insert - stereo - logic - special - pitch shifter ll) will do it. just set the mix to 100% and set the semitones to where you want it. however if you're going for a smooth bend it will be more complicated. you will have to automate the cents and the semitones consecutively which may take a while to achieve. theres probly an easier way maybe in the sample editor? i havent found an easy way to do it yet

Why don´t you just use that audio section as a sample in whatever software sampler you are using and use the normal pitch wheel function?
