Korg's latest addition to the Volca line is a dedicated Kick Drum module, with a sound shaped from an MS-20 filter. While not a traditional drum synth like Roland's offerings, this does provide a classic analog richness with its own character.
Korg has also announced a trio of in-ear metronomes designed with specific markets in mind. There is a synchronized metronome for musicians to keep time together, and a similar one for ballroom dancing. There's also one that's supposed to make you good at golf, because reasons.
Here's a demo for the Volca Kick, featuring Chief Engineer Tatsuya Takahashi jamming out on his creation!
An analog kick generator that delivers powerful sounds from kick drum to kick bass. More about volca kick at: http://www.korg.com/volca_kick/
Chief Engineer Tatsuya Takahashi demos the analogue kick generator based on the MS-20 rev.1 filter in oscillation. All sounds created by one volca kick and one volca sample.
