First real laser-based MIDI Controller (beyond the mere on/off)

Digital Dynamic Geometry, patent pending. Measured data are:

  • Direction vector (up to 3 parameters according to version).

  • Speed (one must exceed Mach 0.85 to possibly lose a beat with a Ø 6 mm rod)

  • Longitudinal crossing position.

The useful length can range from a few centimeters to several meters and use visible light beams like a laser-harp.


  Back & forth Pedal use


For example, in musical instrument mapping mode:

  • A new musical gesture with control of the pitch, dynamics and articulation

  • Great for improvisation

  • Excellent visibility and legibility of gesture by the spectators

  • A contactless play but by manipulating a baton (or a broomstick, or a rope, or a led foam stick, or ... nothing, just fingers).

  • A really intuitive use...     really

  • We are facing a real object that can be positioned and adjusted

  • A good visual feedback even with low power lasers. Cutting laser beams with a stick produces bright persistent spots.

  • Widely customizable and configurable

  • Finally, very "fun"

Speed and Accuracy + Bosch drill :-)




DJ Samples loop trigger.

If the velocity is not used for example to trigger samples, the size and the position of passage of the object determine the MIDI Event. Here with one finger, the flat of the hand and a 5mm baton.

The system is strictly digital, a determined movement always produces the same effect, it is absolutely not an analog proximity sensor (kind D-beam Roland).
