i'f you can get your head around midi yoke this wee thing is excellent.
The best for me is the trippy x/y pad. great for those filter cutoffs on your favorite synths
.Very intuiative and flexible to use the DS pad to draw on your automation. I have emailed the programmer with some ideas e.g a step sequencer with visual feedback ala monome. Dunno if this is possible but being able to turn clips, racks scenes on/off and keep track of it all on the nds would be sweet.
