The problem could be definitely solved if M9 / M13 would have an USB connection and some „M9 / M13 Edit“ software where you could save, manage and edit all presets, scenes and parameters like in POD HD line.
There is no need to have M9 / M13 working as an recording interface / sound card (it does not make sense if there is no amp modelling in M line), but the editing software could be a really powerful tool.
