This post is for all those who own a Marshall CODE of any version,
to report their failures or issues when installing the new Firmware 1.46,
since there are many problems that this has caused to users and it
is worth collecting said errors to request to Marshall the necessary
corrections in a new version.

Hello,

My footswitch stopped responding under the following scenario.

Marshall Code 50

Four button footswitch

Macbook pro connected via USB

Sound output set to Marshall Code

Playing Youtube videos through the amp and playing along

After a while, the footswitch stopped responding. I couldn't change banks or position within a bank.

Unplugging the USB cable seemed to get things going but footswitch stopped responding again shortly after.

Turning the amp off an on again resolved the issue.
