I really dig this work. Been wanting something just like this! I find myself beatboxing here and there randomly, and sometimes i really brew up something nice. Would be awesome to have a great way to catalog these "beat-deas". I can envision this app as an easy means for me to pop out of my pocket real quick when i have a good one. Would be nice to have the original beatbox sample saved as well for a reference.

From there - getting this (beat pattern at the least) into something like Ableton (or some importable format beat format (does that even exist? (Inception!))) would be so awesome.

The biggest thing for me would be for it to be able to handle a pretty complicated rhythm. When i get goin, its a lot faster than your examples (and i'd imagine 2 notes hitting in the same place create a problem as well). I'd imagine it gets pretty complicated pretty quick.

Maybe even a way to record a beat, have it do the conversion, then record over it to make more complicated rhythms.

As you can see i'm excited about your product, and am probably getting way ahead of myself on some of the comments. But either way, keep it up, and let me know when i can try it myself. Thanks!
