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 | 5•3 | |
overdubbing, including JM4 Mixdown files. This greatly extends the functionality of the | ||

•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.
