I just got around to updating the firm ware on the code 100 thought as long as i had the amp connected to my pc via the usb cable I would check out the code editor and it would not respond looked at the manual casually and did not notice any mention of how to connect
dos this need to be acomplished using a midi to usb cable
Can you confirm which Code Editor you are using, on our My Marshall website you cannot edit only download presets.
If it is the Marshall Tools website this is not a Marshall product and we have no support for that website,
Check that when you try to connect via code editor you don't have open my.marshall.com or marshallcode.tools websites because code may have only one midi connection at time
