Automating Pitch Correction... rough


Recommended Posts

I have a concern with the Pitch Correction plug-in, an issue that arises from automating it (on vocals tracks), the note, scale/chord type and response parameters.


Logic does not consistently 'catch' these changes in automation during playback, so you'll play back and hear one thing (i.e. the way it should be playing) and then you'll play back and hear something different (because it's reading the automation just before/after that spot).


This is especially frustrating when bouncing, because the vocals come out inconsistent. One bounce will come out one way, and the next bounce will sound different- in those areas where there's intricate Pitch Correction automation.


I sometimes split the erroneous parts of the audio regions and drag them onto their own tracks, isolating them so the automation is accurately detected (which works but is a lot of trouble)


I am hoping Logic steps it up with Logic 10 in terms of it's ability to catch every nuance of automation... Would more RAM or any kind of system upgrade improve this? Also, how about third party plug-ins, could they be effective? Antares AutoTune?

Ski, really? so I'm not alone :) Yeah, I think I'm going to have to go with a 3rd party plug-in.


Rickenbacker, I've heard good things about Melodyne, I knew it could be helpful but I held off on it to see if I could pull off what I'm trying to do without it.


Thank you both for the reply.

Disclosure: I'm not connected with Melodyne in any way. I just use it.


Get MD if you can afford it. My only real complaint is that Celemony (the developer) is located in Germany(?) and only do email support. They will not take a phone call, nor will they log on with GoToMyPC (or equivalent) to help. They are prompt though, within a day with their emails, but there is definitely a subtle language barrier.


Melodyne works as a plugin. You actually record your track or portions of it into MD (after recording/comping your track in Logic, or whichever DAW). Then Melodyne analyzes your "Transfer" as it's called and creates visual "blobs" (notes) with pitch variation wave forms available if wanted. You can go nuts from there. You can change pitch, pitch variation, pitch drift, timing, fomants and more. Of course, you can shorten or lengthen notes too. And the results can be very natural sounding.


However, if you're looking for the T-Pain/Cher type of computer sounding voice, MD is less easy to do than I believe AutoTune (though I'm inexperienced with AT).


Another aspect of MD some folks find useful is the ability to analyze chords into their individual notes (called DNA technology) and you can even alter individual notes within a chord. For example moving E in a C major to Eb, thus making a C minor. DNA is only available in certain versions of MD.


On last thing: SInce you're making recordings of your recordings, you will have more files to manage and project size will be larger. There are directory (path) settings to help but transfer file names are cryptic computer-generated and have zero meaning to humans. MD seems to manage these files well, though, but be forewarned, you are working outside Logic and asset management may be an issue.


Hope this helps you and anyone interested.

Yes, I've done that, but it never sounds so computer-like as Cher/T-Pain. Maybe it's just my voice. :?

You can do this with the Logic Pitch Correction plug-in as well, response = 0ms. Try singing off key if you want to hear the effect even more. The more off key, the more the plug-in will have to work and the more T-Pain effect. On the other hand if you're way off it will take some work to select which notes you want the plug-in to correct toward.
