Apparently some peeps at TGP were unhappy because you have to actually tap twice to change patches. What happens is that when you go to a preset it defaults to control of each individual loop, so you can switch individual fx in and out within the patch. This necessitates "priming" it by hitting preset before you switch patches. Not a big deal in all reality. Take with a grain of salt, as this is not first hand info.
Anyways, it doesn't weigh much in my decision to possibly acquire one down the line. If I can afford more at the time I may go with a Midi G-Labs system or something though.
