Any X2 disk containing a load ALL function includes a PCG file(Program,Combination,and Global) any time one of these are loaded from a factory disk it will default the polarity for the damper. What needs to be done is having the file loaded into the X2 and also having the polarity at the desired setting resave everything ( save as ALL) onto a new formatted floppy. Use the new floppies instead of the factory ones.
