KORG KAOSSILATOR, comes with box, manual, and dedicated adapter. You can easily create loop music by setting the key, setting the tempo, selecting a sound from 100 types, and recording in 8-bar increments. You can create a decent rap accompaniment with just rhythm patterns and bass, and if you raise the BPM to 300, you can create truly chaotic phrases. By swiping the touch pad horizontally, the pitch changes, and vertically, the sound quality changes, so you can create loops quite intuitively. I think it's a very excellent and innovative input device. Operation has been confirmed with the dedicated adapter, but for some reason, it didn't work well with batteries. I'm not sure if it's poor contact or if the batteries need to be new, but it's a fairly old device, so please manage accordingly. It comes with a rather rare dedicated adapter. Recording, sound changes, drum machine, and other functions worked without any problems. For some reason, everyone was selling it at a premium price, so I'll join in. Please use the coupon while you can. I think I'll lower the price when the coupon is no longer available.
