Loops
JM4 loops come in 2 flavors, either as part of a recording that you created in the JM4, or
as a WAV file that was either mixed down from a JM4 recording or imported from your
computer. Loops created in the JM4 will always work together with the Song or Drum
track you started with, but there are many other creative ways to work with loops. Here are
two examples of how you might use WAV files to create multiple loops in the JM4:
Record multiple overdubs to your original loop, then mix them down as individual •
WAV files using the Playback Level controls to mute the other tracks. Build any
number of tracks that will sync together, then edit and mix them in your DAW.
Create custom loops on your computer, then import them into the JM4 for jamming,
•
performing, or further overdubbing. As long as your imported WAV files match the
exact length of the original reference loop, they’ll sync and loop together perfectly.
Any mono 16 bit 44.1 WAV file can be imported and looped in the JM4 for further
overdubbing, including JM4 Mixdown files. This greatly extends the functionality of the
JM4. To demonstrate the possibilities, here’s a multi-track tutorial you might want to try:
Press the • SONG button, navigate to the Drums tab, then turn the wheel to select
095 Straight Groove (or use any other Drum track). Press the R Arrow to load it.
Press the • SONG button again to display the Tempo/Pitch Modes menu item. Select
it, then press R Arrow and turn the wheel to select Time Stretch. Set the tempo to
101 bpm. Press RECORD and watch the count in the display. After 4 bars, press
STOP.

You just created a 4 bar drum loop at 101 bpm. Now select an Amp Model that •
sounds good to you, press PLAY and jam along with the Drum track until you have
a rhythm guitar part that works with the drums. When you’re ready, press RECORD
to overdub your guitar part. Play for 4 bars then press STOP. Listen to your take. If
you’re not happy with it, press UNDO to clear it, press RECORD and overdub your
guitar part again. Repeat the process until you have a guitar track you like.
