Why don't you have a Windows App? For me (and I believe for many other users) is really annoying to control my Marshall Code using cellphone or mini tablets.
I really think it would be very welcome an App for Windows, so we could use our notebooks or lap tops to control presets and tone of our Marshall amps, under a better interface, bigger screen and together with other music software.
Otherwise, I am very satisfied with my amp.
There is a third party software https://marshallcode.tools/pc-editor/ which works really fine. It allowes you to controll all presets in very easy way, and store presets as files on your PC. As I sad it's not a Marshall product, so Marshall does not support this software, but it's definitely worth trying.
Cool! That's it! I will give it a try right now.
Thanks for your support.
All the best
