Hi,
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.
Regards,
