CONTINUUM FINGERBOARD

The Continuum features a touch-sensitive neoprene playing surface measuring approximately 19 centimetres (7.5 in) high by either 137 centimetres (54 in) long for a full-size instrument, or 72 centimetres (28 in) long for a half-size instrument. The surface allows a pitch range of 9350 cents (about 7.79 octaves) for the full-size instrument, and 4610 cents (about 3.84 octaves) for the half-size instrument. The instrument has a response time of 1.33 ms.
Sensors under the playing surface respond to finger position and pressure in three dimensions and provide pitch resolution of one cent along the length of the scale (the X dimension), allowing essentially continuous pitch control for portamento effects and notes that are not in the chromatic scale, and allowing for the application of vibrato or pitch bend to a note. A software "rounding" feature enables pitch to be quantized to the notes of a traditional equal-tempered scale, just scale or other scale to facilitate in-tune performance, with the amount and duration of the "rounding" controllable in real time.

The Continuum also provides two additional parameters for the sound: it is able to transmit the finger pressure on the board as a MIDI value, as well as the finger's vertical position on the key. These parameters are independently programmable; a standard configuration is where position on the X-Axis (lengthwise) on the instrument corresponds to pitch, position on the Y-Axis (widthwise) corresponds to a timbre shift, and position on the Z-Axis (vertically) corresponds to a change in amplitude. The Continuum is capable of polyphonic performance, with up to 16 simultaneous voices.
Each recent revision has brought more features and sound diversity to the internal synthesizer in the Continuum Fingerboard. As such, the instrument is starting to be both a controller and a stand alone instrument.
