The Tony-b Machine can be run entirely with your mouse or keyboard. The middle row of keys selects the melody note (as shown by the keyboard), the top row shoots out a sound sample (some might sound familiar), some bottom-row keys change the tonal key that the bass and accompaniment play in (a, d, or e minor), and the number keys change rhythms, add percussion, and fill your computer's room with smoke and flashing lights. (Not really, but that'd be cool.) Hitting other key combinations triggers more awesome samples to suit your techno fancy. You can even record your mixes to play back and edit your jams!
Analysis: While it's obviously not something you'd want to use on a paid gig at a nightclub, the Tony-b Machine has enough bells and whistles to make it good wholesome fun and with a quality beginner's interface. Granted, there are some basic functions that I felt were missing from this system (changing tempos, more freedom with chord movements, switching to major keys, etc.), but still a fun toy to play with. I spent a good chunk of time fiddling around trying to make a techno version of "I'm a Believer."
So if you're ready to get your groove on, get the party started with the Tony-b Machine!
