Analog Four restore and transfer problem

if i do factory reset, all my patterns and sounds will be gone, right?

No. Empty Reset will do that, factory reset will only reset the contents of project 1 and sound banks A and B. Other content on the +drive will not be affected.

is there a way to backup?

The forum search feature finds info like:

Should work the same in Transfer or any other application for sending and recieving sysex.
