How To Make Green Apple Loops  [ Edit ] 

As of Logic 7.1 (Pro or Express), you can make green Apple Loops in addition to the blue kind I have demonstrated previously. The green ones can be dropped onto any track type — if you drop them on a MIDI or audio instrument track, Logic will load a sampler (or Garageband instrument) to match, and show the MIDI region. If you drop them on an audio track, you’ll get the rendered audio.

The procedure is really simple:

  1. Create an audio instrument track and load it up with your favorite virtual instrument. I’m pretty sure Logic likes to have audio with the loop — in other words, don’t use a MIDI track that drives outboard gear. You can make Apple Loops that way, but you won’t get a sound preview for them in the loop browser, and you won’t be able to use them on audio tracks.
  2. Make sure your time signature and key signature are setup correctly in the Logic song for the material you’re performing. This isn’t strictly necessary (especially for drums), but it does help make sure your loops preview as expected in future Logic songs. I forgot to mention this in the video. What can I say, I play drums primarily.
  3. Record a performance. In the video, I use the canonical four-bar drum loop, but it can be whatever you want.
  4. Choose Region > Add To Apple Loops Library….
  5. Choose the relevant metadata (name, type of loop, and so on), and click Create.

That’s it. After that, you’ll have a new loop filed under My Loops in your Apple Loop Browser. The video shows this procedure for the visual learners in the audience.

Further Notes

  • After you’ve created a green Apple Loop, do not edit it in the Apple Loops Utility if you want it to stay a green loop. The Apple Loops Utility seems to strip out the MIDI data. You’ll have to recreate it from the source MIDI region.
  • This procedure works great with stereo virtual instruments. If you’re using an instance of, say, the EXS24 in its multi-out configuration, you might have to put in some more work. Or maybe it just won’t work at all. I haven’t delved deep enough into this to sort those issues out, but I know that the first time I tried this, it was with a multi-out EXSP24, and no audio was in the loop file.
  • If you want effects to be included in the channel strip with the audio instrument/MIDI version of the loop, only use inserts. Any send effects you use will not be included in the channel strip. The rendered audio will include your sends and inserted effects, which is nice, but can cause confusion with your users (yes, I’m looking at you, Apple).
  • The drums in the video are the beautiful and talented ns_kit 7, the now discontinued free version. The full version is available from a different company who has recently taken it on.

Update 4/17/08: There’s another video tutorial that shows the same information (and more) in Logic 8. One thing that I missed here that is covered in that video is what happens when you share a green loop with someone who doesn’t have the plugin you used — in short, the loop loads with the plugin name crossed out. In the case of drum loops, there’s the simple fix of swapping in your favorite sampler or drums plugin, and off you go. For synths, it could be more complicated. Deepswing Productions, the maker of this other video, has many other Logic 8 video tutorials available as well.

Hi Joe, How do you removed/backup user generated green midi loops from the apple loop browser in logic 8? I can't seem to find any info in the manual or on any forums..

Thanks in advance.

Josef,

There are a couple of Apple articles that will help you with this.

This one tells you where all the loops are stored:
http://support.apple.com/kb/HT1045

Your own loops are probably stored in ~/Library/Audio/Apple Loops/User Loops/SingleFiles, so if you go to that folder and move all the loops out, you can back them up.

If you want to rebuild the Apple Loops Index, which is what determines what shows up in the browser, follow the instructions here:

http://support.apple.com/kb/HT2443

It would be nice if there were a "rebuild index" button right in the loop browser so one wouldn't have to delete files first, but this seems to be the only way right now.
