changing pitch of loop

[savage_g]

Fairly new to using logic and getting frustrated trying to do something very simple.

I have a 2 bar loop that I've dropped into my sequencer, and all I want to do is adjust the pitch of it (NOT by timestretching which I know how to do, but by dropping the pitch by like 3 semitones so the the length of the loop increases accordingly)
like this - http://i65.photobucket.com/albums/h204/sanageg/Picture1.png?t=1232060953

So the length of the loop almost matches 2 bars of the project tempo, then I can fit it exactly by timestretching.

In nuendo this was really simple to do (right click on the audio region & change pitch), and I',m assuming it's just as easy in Logic and I'm just missing something really obvious.

Any help would be much appreciated.

Maybe load the sound into Ultrabeat. Trigger the sample at the pitch you wanted. Bounce the sound out. And then use the timestretch to get the new pitched sound to fit your 2 bar tempo.

I don't know a faster way to do it.

The MPC lets you Patch phrase so you can change pitch but retain the tempo in real time but you have to do a little work before hand. So Logic requires a little work to give you different pitches of samples.

I know Logic handles changing pitch of notes very quickly but not samples.

Thanks man - was doing the same workaround with the EX24. Just thought it was weird that there's no way of doing fairly basic audio processing.

I totally understand.

This was one of the major reasons I bought an MPC2500. I thought it could change pitch faster than Logic. From what I can tell, all major music equipment and software can change pitch relatively easily. The problem that surfaces is changing the pitch but keeping the tempo the same.

But I don't know of anything that can do that on the fly. The algorithm needed to process that info is too complex to be done in real time instantaniously by anything that I know of. You see how long it takes logic just to take something that is as short as two bars and adjust it's tempo. There are too many factors that have to be taken into account to be able to produce decent pitch changes. Is it a vocal sample? Is it a drum sample?

In Logic, you have to tell it which algorithm to use before you apply it. And in an MPC, you have to do a little work before you patch phrase it which then allows you to trigger different pitches while staying within tempo in real time. And once you do, you no longer have the option of rearranging the loop's pattern. If you do decide to change the chop up, you have to start the whole patch phrase sample process over. The cool thing is, when you do it, you can adjust the tempo to anything while it plays and the MPC will change the tempo without effecting the pitch.

This guy might know something I don't though...

Exactly what Om said, they don't work very well for samples. But you could check out these logic inserts:

Pitch Correction
Pitch Shifter II

I personally don't use them tho, I just load the sample into Audacity.

Pitch Shifter tends to degrade the quality of the sample though.. its a dirty fix, that should not be used if your serious about your production.

fruity loops can do that to a 2 bar loop in seconds

Just click on your 2bar loop to mark it. Open up time and Pitch Machine window by using the key command control+P

Or alternatively from the Sample Editor's menu under "factory"

Here you can change tempos or transpose your audio to your liking. Leave the tempo as it is but edit the transposition section to 3 semitones like you wanted......

P.S transposition is calculated in cents here so if you need to go 1 semitone up, dial up 100 cents and vice versa....

Another thing. Check the Harmonic correction box to avoid the Mickey Mouse effect where all the fundamentals and the "formants" as in the upper harmonics of your audio are pitch shifted as well. This is to maintain the original timbre of your audio. Only thing is that it takes a lil bit more time to process the audio but we are talking seconds here so.....

Hope this helps.
