Can you download your own presets in the sandbox and then save them on your own mod device?
In general, I like the idea of creating presets on your own $computer, independent of the mod device, and then saving them to the mod device. To create basic ideas of effect wiring (effect blocks (*1)).
Also I would like to be able to create certain arrangements of effects and connections directly on the device.
(*1) Effect blocks:
You can select a range within a preset and move/delete/… in the GUI and/or save it separately as a new effect block. Within a preset you can then load individual effect blocks into the existing preset.
