The KB2D Laser Harp Controller is a detection system working as a MIDI controller. It enables to send customizable MIDI messages just by touching / interacting with laser beams, and can be used with any laser projector system in order to create an interactive projection. With the various detection modes available, it can be adapted to any show, from the easiest laser Harp system to the most complete Interactive “laserman” show and does not require any communication or synchronization with the laser projector. Thanks to an exclusive and innovative detection system (patent pending), it is actually the most compact, competitive and versatile Laser interactive device on the market. The KB2D Interactive device can be combined with a 45° mirror to project the beams vertically for a Laser Harp configuration. Lightdiction proposes a special Mirror holder for this purpose. Both KB2D device and KVANT laser projectors can be fixed on it at the same time Footswitches or other external MIDI controllers can be used to improve the flexibility of the device during shows.

(*) Other sensibilities available on demand, in order to fit with the power of the laser to be used. It is still possible to attenuate the power received by using darker gloves for instance (or bare hand instead of white gloves). Maximum and minimum distances are just indicative and should not be considered as very accurate.
