HI, I'm really considering buying these as I tried them at a friend's home studio and I loved them, specially the Thrash version. I don't have access to any documentation nor manuals (Since I don't own the product yet) and I'm trying to see if I can switch between presets with my Midi controller for live playing. I have not been able to find anything so far. Can it be done on the standalone version? Or do I have to use a DAW to achieve this?
