I love looping - a lot!
..But I don't see this feature within the KPA.
I don't think it is possible without an upgrade, and if the board is supposed to do the trick, why not use the same amount of money to buy a separate looper (like the Boss RC-3) and keep the price down for those who doesn't need it.
I have an old Boss RC-2 for this, and it really does the trick. It is even a pretty cheap gadget.
