REAPER facilitates working with files that consist of sets of groove slices, such as REX files. These are created in and exported from programs such as Recycle, to be used in the creation of tempo based music. You can import these files into REAPER either using the Insert, Media command or by dragging and dropping from the Media Explorer. When you do this, they will automatically position themselves according to the current tempo. Once you have imported your files into REAPER, you can manipulate and use them in exactly the same ways as you can use other media items that have had dynamic splitting applied within REAPER. For example, imported REX slices can be made to keep their beat location even if the project tempo is changed. In your Preferences settings, under Media, Import, there are a number of options for how these files are to be treated. There are several options for interpreting embedded slice information, or you can choose Always prompt. There are also options to determine how Slice tails are handled. Similarly, you can specify how media with embedded tempo information is to be handled. Refer to the information in Chapter 21 more details.
The Action list also includes a useful action Item: explode REX item into beat slices. This can be assigned its own shortcut key if you wish.
