Gabriel Aulaga Posted November 5, 2007 Share Posted November 5, 2007 I want to apply a linear 100 cents pitch bend in an audio file, lasting one measure. Using Pitch shifter it is possible to apply a 50 cents pitch bend, but not 100 cents. What is the best way to do it? Gabriel Link to comment Share on other sites More sharing options...
muses Posted November 5, 2007 Share Posted November 5, 2007 Yeah, crazy, huh? You could try to automate it such that at the exact moment you get to 50 cents, you switch the semitone up by one, send the cents back to 0, then start raising the cents again to 50. It'll take some experimenting to get it to sound smooth, but it can work. Or another option would be to start a semitone higher, but your cents at -50, then go all the way up to +50. They're workarounds, but I can't see any other way with Logic's Pitchshifter. Link to comment Share on other sites More sharing options...
Gabriel Aulaga Posted November 5, 2007 Author Share Posted November 5, 2007 Thank you very much for the prompt reply. I already tried what you suggested. The problem is that there is a strange sound at the beginning of the transition. Apparently the audio system is not able to process efficiently simultaneous semitone and cent orders. Regards.

muses Posted November 5, 2007 Share Posted November 5, 2007 Ok, here's another workaround (man, you really got my brain moving this morning, and only on one cup of coffee ). What if you were to bounce down the audio file a semitone higher, then use the pitchshifter on the new bounce at the point when you reach +50? You may need to put it on a separate track to make it sound smooth. Link to comment Share on other sites More sharing options...
fader8 Posted November 5, 2007 Share Posted November 5, 2007 Gabriel, If you want it really smooth, load the file as an EXS sample and automate it with pitchbend. The Apple AUPitch plug-in may work for you too, but its resolution is coarse as it has a 4800 cent range. But you could try it. Link to comment Share on other sites More sharing options...
Gabriel Aulaga Posted November 6, 2007 Author Share Posted November 6, 2007 Hi, Muses, Your solution is fine!: bouncing one semitone higher and making +50 followed by -50. It is smooth and simple. Hello, Fader, I think that using EXS is fine, but just too cumbersome. AUpitch is too coarse. Logic should have made Pitchshifter with a greater cent range. I am using this effect in a rock song. At the end of a chorus, theres is a sustained chord lasting one measure. I am introducing this pitch bend in the output track for all the instruments at once. Right after the one tone pitch bend, the verse begins. The effect is dramatic. Thank you very much for your hints. Gabriel Link to comment Share on other sites More sharing options...
