I can become the next Skrillex with this keyboard.
The idea is pretty cool, but the sound that emits from the keys is way too harsh sounding. The sine and triangle waves are not that bad, but the square and sawtooth waves almost give me a headache. I wish you were able to play more than one note at a time so you could make chords and stuff. A recording feature wouldn't be terribly bad either.
Overall, there's not too much I can do with this keyboard except.. tap keys, but other than that I think this is a pretty good game.
