Hi,
What do you mean with using "screenshot"?
The favorite mark is part of the preset.
Only banks and individual presets can be exported.
If you are on windows and wan't to move your presets to a new PC, then i would think it's possible and most simple, if you copy your Arturia folder in the hidden folder ProgramData (not ProgramFiles). Be sure to enable the PC to show hidden folders.
If you rename the Arturia folder on the new machine after you have installed all the applications, then you can return in case it don't work. But i would think it do work, as long as the folder that's used is named Arturia. You'll have to try it out. I have moved presets in individual sub sub folders this way only.
On a MAC there must be a similar possibility i assume.
