If you're unfamiliar, Korg's Gadget app offers sequencer and mixing tools as well, so you can create full tracks with the library of tones the $20 app carries with it.

All three of those are available now inside the main Gadget app, and for a short preview of the audio, watch the launch trailer down below.
