It shares many of the same qualities that have made the Pocket Operator series such a hit, such as its streamlined workflow that lets you lay down phrases and beats in minutes. The PO-20 Arcade's claim to fame is a powerful chord engine and 128-pattern chaining, which allow you to achieve remarkably sophisticated results fast. And once you've laid down a sequence, you can get even more creative with 16 delightful punch-in effects. On its own or sync'd with other compatible gear, the Pocket Operator PO-20 Arcade puts creative electronic music in the palm of your hand.
