Is it possible to copy existing presets from an MC6 MkII to an MC6 Pro (excluding color coding)?
Yes, works fine. Export presets or banks or the whole backup and import into the Pro. You’ll need to check any messages that reference other presets or Pages (for example, the Toggle Preset message) as the checkboxes will likely need amending.
Or you can open an editor for both devices in two separate Chrome tabs and copy / paste between tabs
