Re: How to break up samples in Logic Pro 8?

If you use the marquee tool, you can turn selections to regions, but do this in the timeline, not in the sample edit window. You can also set a hotkey to the "split region at playhead" command, and just tap the key as the music plays, and watch logic chop up your sample. Or, you can move the playhead along the timeline and split wherever you want manually.

Garageband automatically created what Logic sees as regions, and Logic, by default, creates an alias of the part you have, and will adjust all of them unless you specify it as a new region, so be careful for a while as you learn Logic and are dragging copies of regions around in the timeline, so you remember which key commands create a new region and which key commands create an alias. Holding down the right mouse button brings up all kinds of contextual commands, I would suggest looking at those to get a really good feel for what you can do where.

Also, Just Blaze has a good tutorial on YouTube about how he uses the hotkey method to chop up samples.
