and now for the importing and recording process itself:
== item manipulation ==
#ensure you are at the start of the project or at a place you feel at ease when recording. Most people like to leave a two bar empty space as a precaution.
#double tap the insert key or use the insert menu, and then choose media file.
#locate your mp3, wav, whatever contains the backing track, and press enter on it. You will notice that a track ahs been created with the file name as an item inside that track. When importing multiple items at once, reaper will prompt you for what you wish to do. Options are self explanatory.
#Once the file or files have been imported, it is time to create new tracks and record, just as described previously.
