Back in April, Korg unveiled its Volca series of mini-grooveboxes. Now, with the release of the Volca Beats, Bass, and Keys on the way next month, a new video series has surfaced in which hardware designer and chief engineer Tatsuya Takahashi highlights the features of Korg’s newest sound toys. As the videos show, Takahashi has really managed to fit a surprising amount of useful and creative controls, as well as intriguing sonic options, into the compact, mostly analog-driven Volca units. Three videos detailing the functions of each $150 piece of hardware can be watched below.
