you should not invest much time into reading and modifying rig preset files. there will be changes and those will break your effort. take this hint as a friendly gesture to save your some time, please.

It's ok with me - thank you for the info. Just better know what is not worth the time .I only want to give some editing possibilities of the amp parameters and fx parameters in off line mode - not meta data (copy set up of fx'ses, amps params and cab params and so on). So your want to add hash code the kpir files?
