Wow, OK. I think I have read this advice in one form or another before but the way you put it just made a light bulb go on.No need. The FACTORY folder in your Kronos HD has all of that.
So you're saying I can create a project folder on my thumb drive, do a save all on the PCG, to that folder, and then I can monkey around with things like crazy. Load 3rd party banks. Make tweaks to factory patches and write them, etc.
Then I can save my project PCG at the end of my session to hold onto all the changes I've made.
If I want to restore to factory, just because, or to find some factory sounds for my project that I've overwritten in my project bank, I can just reload the factory PCG, find some sounds I like, and make a note of the ones I want. Then reload my project PCG and load sounds from factory PCG bank or program at a time into some un-needed bank in my project PCG.
Do I have it right? If so, that's extremely liberating, and it makes the lack of free banks seem a lot more trivial.
