Dave Smith Instruments SYNTHESIZERS

If I use the command "save program" from the editor, will it 
permanently erase the data in the Evolver unit on the corresponding 
program?

And the same question about the editor: where can I save my new 
settings without loosing the programs on Bank 1...4?

I am using the mono Evolver with the SoundTower editor v.2.6.0 on a PC.

My fear is that my usually very tentative editing will destroy the 
factory programs.
