Designer Jeff Snyder shared this video, demonstrating using the unique Snyderphonics Manta controller + the MantaMate Eurorack module. 

• The Manta is a music controller, based on an illuminated hexagonal array touch-sensitive interface.
• The MantaMate is a Eurorack module that lets you use the Manta controller as a sequencer and keyboard for analog modular synthesizers.

In the video, Snyder uses the MantaMate Euro module with the Manta controller as a rhythmic sequencer.

Details on the Manta and MantaMate are available at the Snyderphonics site.
