Query re: Pitch adjustment in Sonar 7

[tunaboy777]

Dear All

I just bought a new electro-acoustic (Tanglewood TW55HB - very nice indeed). Anyway, I charged home from the guitar emporium, drastically overexcited and started recording a kind of thrown together project in Sonar 7. It was only after recording about 5 different guitar parts that I realsed that I had not tuned the guitar to pitch (i.e. it was relatively in tune). Damn. The E string is tuned to somewhere round about a D sharp. My question is, can I re-pitch the audio that I've already recorded? That is, shift all the separate guitar parts up a semi tone plus some finer increments. Any suggestions would be most appreciated.

Cheers
