Continuum Fingerboard

[2] The Continuum Fingerboard was initially developed from 1983 to 1998[3] at the CERL Sound Group at the University of Illinois, to control sound-producing algorithms on the Platypus audio signal processor[4] and the Kyma/Capybara workstation.

A major proponent of the Continuum in contemporary music is Jordan Rudess, keyboardist of the progressive metal band Dream Theater.

[11] He used the Continuum in a piece he composed for the Changing Notes Concert held in Chennai, and in the song "Rehna Tu" in the 2009 movie Delhi-6 and the new version of "Mile Sur Mera Tumhara".

[12] Rahman was particularly impressed with the fact that the Continuum fingerboard could produce Carnatic/Hindustani classical music notes, which is a significant improvement over the piano.

The Continuum, ContinuuMini, EaganMatrix Module, and Osmose were used by Hans Zimmer for his score to Dune: Part Two, with instrument design and performance by Guillaume Bonneau, Christophe Duquesne, and Edmund Eagan.

[15] Composer and performer Derek Duke used the Continuum in Blizzard Entertainment game soundtracks, including StarCraft II: Wings of Liberty, World of Warcraft, and Diablo III.

Throughout the series he used it "melodically, both for aggressive, distorted colors for the U Boat; and for softer flute-like timbres" and for "musical sound design textures for tension and suspense.

"[19] Other musicians using the Continuum include John Paul Jones, Lou Reed, Randy Kerber,[20] Amon Tobin,[21] Sally Sparks and Thereminists Rob Schwimmer, Andrew Levine, and Grégoire Blanc.
