Rex and Acid Files. So with Rex Files, what Rex Files allow us to do is to take individual slices of our audio and then have them automatically conform to our tempo, unlike Acid Files where Acid Files would keep track of our file's speed or the tempo as well as the pitch. Rex Files aren't so much concerned with that. So the problem with actually using Acid Files, if we had a drum, we'd know what the tempo is and we'd speed things up or slow things down. It would keep it in the right pitch but you know what? They'd actually stretch the audio, much like elastic audios. So we may not want that. We may not want the audio to stretch. If you hit a snare drum, it's not going to elastic any longer, whether you're playing a slow tempo or a fast tempo. So the speed stays the same. So Rex Files, Propeller Head went and said, you know what? Let's make these files that actually are sliced up and these individual slices will be placed on our beats in our mid software. So you can do this with Propeller Head's Recycle and create these Rex Files, Acid Files from Sony's now Acid; not originally Sony, allows us again to time stretch these. So where we're at at this point, you've probably heard of Apple Loops and all these other formats that are out there. These are similar. Apple Loops would be similar to our Acid Files with some other fancy features. So just working here, Pro Tools is not working with Apple Loops but it does allow us to bring in Acid Files as of Version 7, as well as Rex Files and it will conform to our tempo so we would want to check this. Keep in mind that when we're doing this for normal audio files, it's looking for beats, where this is already pre-assigned beats. So I've got some Rex Files, it's the RX2 here. And it's conforming to my session tempo. So we'll bring this out to a track, we'll import that and these are a bunch of individual regions and we've got a preference when we import these files, how do we actually want to treat these or how do we want to work with these files? So change the tempo after the fact, go back to the start and now we can have multiple files play together in our session. So I'll bring this down to gray area, it's importing that, Task Manager pops out and it says working on it. As soon as it becomes active and then we can play this. Move this over and while that's doing that, let's go to our Preferences and when we import our tracks, so in our processing here we can choose how we actually are working with this so when we drag and drop on the Desktop, do we want to actually have these conform to our session tempo? So we need to make some choice and that's what our preference is here. We also have the option when we import these, do we want to actually have these as region groups, which we didn't have checked and then create fades individually on these individual slices because keep in mind that with Rex Files, they are individual slices that get broken up. So the slower you do your tempo, the more gaps that you'll hear. But again, the file length stays the same. So that's the advantage of using our Rex Files. This still hasn't finished doing its calculation. And you can see that this is actually conforming to our tempo.
