Quick Start Guide
1. INSTALL THE KB2D USER INTERFACE
Last version of KB2D User Interface can be downloaded on the following link: https://lightdiction.com/Ressources
The name of the program is KB2D_v3.0_setup.exe (version and build number may vary, you should take the last version).
Install the program on a computer with Windows OS and launch it. If the program does not start because some files are
missing, install “vc_redist” package:

2. LACE THE KB2D
If you have a KVANT Laser projector and the mirror holder by Lightdiction, attach the KB2D and the mirror as shown on the
following picture:
Else, just place the KB2D in front of your laser projector to have a position similar to the one on the picture above. The window
of the detection system should be centered (approximatively) relatively to your laser emission point.
3. CONNECT THE KB2D TO YOUR COM UTER
Connect the KB2D to your computer with the USB cable. It should automatically install the MIDI drivers after a few seconds.
Then, start the KB2D User interface. It should show the following window, with the firmware version and Serial Number
indicated:
If you get an error and the interface cannot communicate to KB2D, close all other programs that may use MIDI ports and
restart the interface. In particular, start the KB2D interface preferably before your DAW.

4. START YOUR FAVORITE DAW
Start your favorite Digital Audio Workstation (or download and install one). Then, connect Midi In (KB2D Interactive) to your
favorite DAW, if it is not already connected by default.
Go to “MIDI and Notes settings” Tab. Select the Notes you want to have on your Laser Harp, in the “Notes parameters” section
(one note will correspond to one beam on your Laser Harp).
Then click on “Send Note 1 (test)” to check that the KB2D is connected and playing on your DAW. This should play the note
corresponding to beam number 1 on your DAW.
5. START THE LASER
Start projecting a Laser Harp pattern, with the number of beams (number
of notes) you want. Go back to the “Global Settings” Tab.
Set the number of beams and the Frames per Second rate of your laser
pattern on the KB2D Interface.
6. CALIBRATE DETECTION ARAMETERS
Try to remove parasitic lights that may disturb the detection
system. Then click on “Detection assistant” to start calibrating
the detection parameters.
7. CALIBRATE ANGLES
Click on “Calibrate Angles”. Then, interact with the first beam. When you hear the first note, stop interacting: the calibration
of the first beam is done. Interact with the last beam, and wait for the last note being played, just like you did with the first
beam.
You can now play Laser Harp, all the beams should be correctly assigned to each note.
You can also improve the accuracy of each beam by clicking on “Learn One Angle” and calibrating each beam one by one.
