The 3B is delivered assembled in its external case: 2mm folded aluminum, 4mm machined aluminum front, epoxy paint, DC/DC converters and Meanwell power supply, the whole demonstrates a hardware quality that lives up to the pleasure that The 3B brings.
On the left (yellow adjustable support) is a 3D Laser/IR, without any danger for fingers and eyes, it is a specific technology called TOF (Time Of Flight). This sensor transmits an image of your hand or any other object that enters its cone of vision, as well as the precise distance between the object and the sensor. The image allows, by analysis, to determine the X and Y position of the hand or the object. The Z height is transmitted directly by the sensor with millimeter precision.
A second identical sensor, placed on the right (blue swivel support), transmits the X2, Y2, Z2 coordinates as well as a GATE G2, allowing completely independent two-handed play.
In the center, two buttons A and B are very sensitive pressure sensors. They transform pressure into voltage available on the A/X2 and B/Y2 sockets. They can operate as two independent sources or as a single source controlled by the two buttons: in this case, button A decrements the value, B increments it and both can act simultaneously to allow excellent control finesse.
Management of height information (Z1 and Z2)
The height of the hand, another part of the body, or an object in relation to the sensor is fundamental playing information and The 3B offers you several ways to manage it.
LIKE THEREMIN mode
When the hand enters the cone of visibility of the sensor, the GATE is activated. The voltage available on Z will correspond to the height of your hand. By default, The3B offers 120mm per octave. With its sensitivity, in broad daylight and without gloves, you cover three octaves minimum. You can change this 120mm reference per octave (possible values 72, 96, 120, 180, 240 and 360 mm)
SELECTED SEMITONE mode
Each 10 mm of movement (with 120 mm/octave setting) corresponds to a semitone. The GATE in this mode is generated for each note played. You can activate/deactivate certain semitones to limit the range to a specific key or notes.
