Hello everyone from Portugal,
Just out of interest, did you get any support direct from Marshall?
Regarding your points.
1. This sounds pretty bad, clearly something major is wrong there, I've never had that happen to me before, I would hope Marshall answer you quickly about it.
2. Yes, "occasionally" mine is the same. For me personally its not the end of the world to restart the app.
3. All amps make a humming noise to some extent, as long as its not crazy loud I think its something you have to live with. Its most likely coming from the power amp section (the real hardware power amp not the emulated one), thats why you dont hear it through headphones.
4. Not strictly true. The CAB feature is supposed to be voiced to work with Code speakers. So you dont need to switch it on or off. Having said that there are no rules and no "do's and dont's" and you wont damage anything so just go with what sounds best to you. If you like it with the CAB on through a real cab then do so, if you like it through headphones with the cab off, then thats fine too.
There is no other software available anyway. My amp came with 1.45, but apparently you can only download 1.44.
Hope this helps
I suppose they would argue that the Presence and Resonance controls belong to the power amp section and not the pre amp section so shouldnt be on the same screen, but yes it would be useful if all the EQ was in one place.
Regarding your amp freezing. Have you tried disconnecting all your devices from bluetooth. I have noticed lately some strange behavier with bluetooth when I have multiple phones/tablets connected to it. Only one is connected at a time, but I think there is some strange interactions taking place. I was thinking it may be worthwhile trying going through any devices you have connected and getting them to "forget" the code to see if that helps.
