Hey everyone.
I'm having trouble using the audiosuite pitch shift in Pro Tools 6.4
I'm recording guitar for all of my bass parts and pitch shifting down 12 semitones. The problem I'm having is that pitch shift also slows down the file so it becomes out of sync. I notice that the "ratio" fader also moves in conjunction with the semitone "course" fader within pitch shift. Do I need to set it up differently? what I'm I doing wrong?
I used the Serato Pitch N Time 30 day free trial and it was supper easy to use. I cant afford the $700 price tag so I'm trying to get the audiosuite pitch shifter to work for me. Any help would be great.
Thanks

pitch shifting by itself will always speed up or slow down your audio material--what you're looking to do is time-stretching (or time-compression). a lot of timestretching algorithms simply can't stretch/compress something an entire octave, but i'm guessing the ratio fader is what you need to adjust here. i've never used pro tools so i can't be specific, but i'm sure the help files/manual explain it if you search for pitch shifting or timestretching.

Actually, I think it is the other way around... Time compression/expansion will speed up/slow down material and can affect the pitch if plug in is set to be more acurate for tempo, and less for pitch. Pitch shifting depending on the settings CAN affect the speed, if you set the plug in to be more acurate for pitch, and less acurate for tempo. Pitch n Time is the best I have ever heard. I have never had much luck with anything more than a few cents up or down in the Digi pitch shift plug in. Anything more and I have always ended up with artifacts (in both pitch and time).

no, this is incorrect--if you pitch shift something what you're doing is either slowing down or speeding up the material, which gives the alteration in pitch, if you've ever used a sampler you know what i mean. time correction is used generally to maintain the pitch of something, while altering the tempo. this gets confusing however because often times pitch shifting algorithms will have time correction settings in there with them, and time correction algorithms will also usually have pitch settings.

basically what you're wanting to do in this situation is pitch shift the audio down an octave, and then use time compression to squish the tempo of the material back to what it was as an octave higher. but dont expect great results--time correction will noticably damage the sound quality of your file with extreme settings such as you're trying to achieve (i.e., an entire octave)

Ah, I see what you meant... Either way, Pitch n Time is the best for the job.

Thanks guys..........I really appreciate the help.
I finally broke down and bought a bass so now I dont have to rely on pitch shifting.

And I agree with you lvjazzman , Serato's "Pitch N Time" is the best pitch shifting software I've heard to date...........
Peace
