I have just purchased a JM4 Looper and can not figure out how to put a backing track on the device. I have downloaded some MP3 backing tracks and have tried to convert them to WAV using multiple audio converters but the JM4 keeps telling me "WAV files must be 16bits 44100Hz mono" after I put the SD card in. I have exported files using Audacity and VLC and set the parameters to the 16bit 44100Hz and mono but I keep getting the same result. Does anyone know of a way to convert MP3 files so they will work with the JM4 or am I missing something simple?
