Really great

If bebot were a sampler and granular synthesizer, it would look something like this. This may turn out to be one of the more useable iphone instruments for me personally.

2 functional things: I can usually make a note stick in stepped mode if I move all the way from left to right. Also, personally I think the range function should work when you are in stepped mode as well, thus you could do away with bass mode altogether.

Wish list: More mangling efx such as distortion (bit degrade?), etc. Possibly a more customizable scale choice a la bebot. Also, it would be great if you could select the direction of the sample being played by sliding your finger forward or backwards over the sample bar.
Anyway, by far the most useful (to me) granular synth/sampler app Ive tried.
