Hello Axel,
[Topic moved here.]
If I understand correctly what you're asking, yes -- to transfer a stored registration from a master general to a stepper frame, just make sure that the setter is off, then press the relevant master general so that its stored registration is recalled to the draw-knobs/tabs, then store the current registration (i.e. the states of the draw-knobs/tabs) to the desired stepper frame (with the setter on, so as to store it).
