Apple Logic Pro /LogicExpress Discussion

I have done this with my midi data in Logic Express quite successfully.. but thus far have not 
done it with my samples. i recorded a guitar piece that didn't quite fit with my bmp... does 
anyone know where a good tutorial for quantizing samples is online?

Thanks, Andrew.

You are supposed to be able to quantize audio in logic, and in 7.2 even 
change the tempo and have the audio change too if it was recorded in Logic. did you 
check the manual? I am pretty sure its in there.

It sounds like there are two questions here??  

1.  How to adjust the BPM of an audio clip

2.  How to quantize an audio clip.

      Adjusting the BPM.  Sometimes if I highlight an audio region it will follow a tempo 
change I make.  Alternatively, I adjust (cut, or add blank stuff with the glue bottle tool) so 
that it fits perfectly in a certain number of measures.  Then I adjust the tempo of the 
session, and double click on my audio region, navigate to the Time and Pitch Machine, and 
enter the appropriate information for adjusting the audio for length.

    Quantizing audio.  I only tried this once in Logic, I tend to use Pro Tools "Beat Detective" 
for this usually.  Ableton Live could make a case for being the best for this type of edit.

     But in Logic:  Make sure the audio clip is at the same tempo as the song.   Then double 
click on the audio portion you want to quantize.  First go to the upper left menu and 
"Create Backup" ... then head into the menu that contains quantize, and you'll probably 
have to use trial/error to get satisfactory results.   Breaking up the track into smaller 
segments (say 4 measures, even 2 measures in some cases) can improve results.  Then 
add crossfades between the region cut points.

     Take care,

        Pete

Are you using Logic 7.2? I think that this was a feature of 7.2 to make 
flexible audio loops that follow tempo changes. I often use the "poor mans" quick 
and dirty method - cut the audio into chunks of 1/4 notes or 1/8 or 1/16 notes 
in the original tempo then change the tempo and add crossfades. This works 
pretty well for drum loops which no change in tone. When I get things more 
finalized I can make nicer edits. For example, opening the little regions and 
adjusting the start and ends, or using the glue tool in the audio window. In fact, I 
never really understood why people like BT would use the time machine on drum 
loops so much because that also messes with the transients. But if you copy a 
little bit of silent audio you can glue it into the sample, then cut some and 
adjust it very precisely.
