PHLIAUZUN Posted October 1, 2013 Share Posted October 1, 2013 Hello Troy, One certain point is that you can only use WAV files. MP3 aren't supported. If you want more informations, take a look at the JM4 avances guide wich is only about SD issues. http://fr.line6.com/support/manuals/jm4 For the firmware, I dont know but if you can't import WAV files maybe you have to upgrade....

Steve_Wilson Posted February 16, 2014 Share Posted February 16, 2014 16-Bit Mono 44.1KHz .wav files are the type file supported. You can always convert the MP3 into a WAV file format or vice versa.

Troy1g Posted January 1, 2016 Author Share Posted January 1, 2016 Hello, Finally Trying this again. I converted the backing track to a .WAV but when I go to load the WAV file from the card I get a message that says Wav File must be 16 bits 44110 HZ Mono, I am attaching my the specs regarding my file, Any thoughts would be appreciated. Also does anyone have some go to WAV files that work with the JM4 in other words some good cover tune backing tracks? Thanks Troy Quote Link to comment Share on other sites More sharing options...
patternbass Posted March 10, 2019 Share Posted March 10, 2019 I just bought a used JM4. Still learning. Perhaps a solution to the MP3 issue is to plug your mp3 play into the mp3 in on the JM4, record the song or a portion of the song using the JM4 record function, then save that recording to the SD card. I assume it would save it as a .WAV file format. Now you could load that song, add overdubs etc. Also note: the newer iPhones did away with the 3.5mm plug in. You'll have to purchase an audio adapter that has 3.5mm male adapter on one end and the iOS lightening adapter. About $6. Quote Link to comment Share on other sites More sharing options...
