Brock360 Circular Keyboard (Gen 4)

The custom-crafted PianoArc circle pushes the boundaries of the musical keyboard experience.    Offering those with the means and the desire the option to take their stage presence (on tour or at home) to another level.   The latest design reflects the experience of multiple world tours and the input and suggestions of the world’s top touring keyboardists.  

We offer customization options to meet your performance and visual requirements.


  • 288 custom machined keys (24 octaves) comprised of four 72-note keyboard sections.
  • Standard “sweet spot” – The point where black and white keys intersect is the same as a standard keyboard/piano.  Yields an instantly playable curved keyboard.
  • Balanced keys – each key is custom machined for an even feel, resulting in a buttery smooth, mid-weighted synth action.
