So Why would a web store like ThinkGeek stock a Korg synthesizer? Well, the Kaossilator isn’t a regular keyboard synth – in fact it’s not a keyboard at all, it’s a touchpad;

Move your finger from left to right to change the pitch of the note, and up and down to change the sound. But musical sounds are only the beginning, the Kaossilator can also be used like a drum kit with dozens of built in beats and drum sounds. Plus you get some amazing sound effects from laser blasts to Pac Man. You can put everything to good use with the built-in loop recording feature which lets you layer virtually unlimited tracks to create complex songs combining lead instruments, drum beats and sound effects together.

Seems like touch interfaces are very stylish these days and that’s a good thing. Touch interfaces are intuitive, and ideally making music always should be.
At $200 it’s a pretty affordable “Dynamic Phrase Synthesizer”. Unfortunately there’s no sign of a USB/MIDI jack, so no data actually exits the box :(
You’d probably have to crack it open to do that . . . So who’s first?
