If I use either the Split function or the Chopper to slice up an event, how do I save the slice points? I have tried Render As, Render to New Track, and Save As from the Track Properties. None of these seem to work.

By "work" I mean that if you re-import the file into a new project, you would still see separate slices. Is that correct?

You are not "slicing" the original media. You are creating time line events that are non-destructively using the original media.

Once you get the "slice" how you want it on the time line, right click on it and choose "Select in Chopper"

From the Chopper, right click on the selection and choose "

"Chop to new track"

This will save out the selection as a new wave file that you can then use as you want.

Thanks, but I understand that part. The question I am asking is how to save slice metadata. I have read several articles claiming it be done.

More to the point, Pro Tools 7 now claims support for sliced ACID files. Specifically they say:

"The ACID file format was created as a “stretchable” and “tunable” format for Sony ACID® software. ACID files are created by Acid and consist of the original audio data (WAVE files) plus metadata about tempo, number of bars, pitch, and slice information. ACID files may not always contain slice metadata."

Although they show examples in their documentation, I have never seen a sliced ACID file. I checked a number of files on the ACID Loops & Samples CD, and none of them have slice information. I asked this same question in the DigiDesign forums, but have not gotten an answer.

I think you are misinterpreting the meaning of slice information. Double-click on the track header of a loop in ACID to bring up the Track Properties and go to the Stretch tab. See all those movable markers slicing through the wave? I believe that’s the slice information that Pro Tools now supports and ACID has had all along. It allows you to move the interpretation of where the beats lie in the wave file. You can move the markers to change the slice metadata and press the save icon to save it.

If you are working with ACIDized media, then the "slice" meta data is part of the file in what is known as the "ACID chunk". When you chop to new, the appropriate meta data is preserved in the new data as well.

PTools docs are using the term slice. We call then stretch markers.

You use the track propreties Strech tab to view and edit this data.

You can adjust existing stretch data or ACIDize non ACID media using this page.

OK, let me try to explain my confusion this way (which is probably more of a Pro Tools question, but I think I have a better chance of getting an answer here):

On the Acid Loops & Samples CD one file, for example, that Pro Tools recognizes as a "sliced file" is ACID ROCK PROMO 01.WAV. If I bring that file into Acid Pro and look at the track properties, it shows as a track type of loop with a stretching method of looping segments.

However, if I bring a non-Acidized wav file into Acid, go to track properties, specify 'loop' as the track type and 'looping segments' as the stretching method, and then do a 'save as' , Pro Tools will not recognize the new file as a "sliced" file.

This thread is really interesting to me as well. I've been trying to figure out the same thing since the first version of Acid! Not with ProTools of course, but does the Acid header just contain basic beat info or can you define actual slice points?
