But somehow I kind of do not like to buy things from IK Multimedia because of their aggressive publicity which they are famous for... I did pay for their recording application (around eight euros) and get two pop up ads every time I use it! I think that as a company they have done a lot to push music making on Android forward it is a pity that they have to shit all over it with publicity!
Maybe they by some accident have not put poop up ads in their amplitube app?
In either case the hardware should be ad free and if I had some extra money would not mind having one of these...
(How about that for passive aggressive... ha ha)
Here is a video from Sweetwater sound demonstrating the interface.
