Copy that!
I have exactly the same problem and frankly this is a fundamental bug as far as I'm concerned. Being able to simply and efficiently manage the sounds in your 4 presets is essential! So far I've found it impossible to transfer anything from "My Tones" into any of the presets! If I could maybe I can then use the gui to promote those presets into Bank 1 ABCD etc but I can't find how to do it and if I could it would still a ridiculously convoluted workflow to achieve something so fundamental.
I think there should be a very simple option for each tone in "My tones" to assign it to Bank 1 ABC or D.
Please release afix for this asap...its really spoling my enjoyment of using teh TT.
