BitWiz brings Lo-Fi sounds with High-Quality. This thing can make some very grizzly-nasty tones, that are not merely messy low-cut-to-death analog wannabes. Advanced patches can even include melodies, sort of like math-driven arpeggios. BitWiz uses Bitwise Operators to shape the sound, an advanced mathematical way of programming, making it daunting for anyone unfamiliar with these concepts. There is a random function for people who don't know what they're doing with it, but that is somewhat limited so you're better off learning to program it.
BitWiz now supports recording and Audio Copy, making it a great source for new original samples. While some app's have gimmicky Twitter stuff, the inclusion of patch sharing via Twitter is quite fun and useful in BitWiz!
Disclosure: I received my copy for review from Kymatica.
