JM4 Looper - SD card problems

Hi,

 

I have the JM4 looper with firmware version 2.09 installed from new but am having problems with SD card functionality.

 

I have tried 2 SD cards now - both smaller than 2gb - and get the same problem.  Every time I try to access the SD card through the looper menu (whether trying to format the card, saving or transfering files from card to looper and vice versa), the looper seems to go straight in to a re-boot or re-start - I never actually get to access the card.

 

I've also tried recording a track and saving it to the card but get the message "invalid characters in filename" despite only using the suggested file name given by the unit.

 

Is the unit faulty or there something I need to do?

 

Also, any chance of allowing playback of mp3 files on the next firmware update? I'm sure this would appeal to anyone and everyone.

 

Many thanks,

Matt

RE: JM4 Looper - SD card problems

 

  Hello,

 

  1) Be aware that you must first store your wav files to the unit, you cannot access wav files directly from the card.

    

  2) Be sure your card is 1-2G in memory, and format the card to the FAT16 protocol using the directions here:

Great - got it sorted, many thanks.

 

I inserted a blank SD card that had been formatted on my lap top to FAT16, then formatted it again in the looper which created the 'Line 6' folder on the card and it is working fine now - I can easily transfer files between my laptop and looper.

 

I've also figured out how to play wav files off the card thanks to another thread - the tracks need to be ripped as mono, 44.1khz 16-bit wav files in order for the looper to recognise them.

 

Thanks for your help!

Forgot to add.... I am also able to access wav files and play them back straight off the SD card (without having to transfer to the unit) and can also save recordings directly to the card as wav files. Happy days!
