The Continuum Fingerboard

The Continuum Fingerboard, designed by Dr. Lippold Haken, is a music controller that is continuous in three dimensions. I helped Lippold out on some of the early prototypes: I wrote some C code for a small version and designed the circuit boards for the first full-scale prototype. But these days I just play it!

You can read much more about it on the Haken Audio site. The three dimensions are X (left to right, typically used for pitch), Y (toward or away from the player), and Z (how hard you are pushing down, often used for volume). I have created some sound files demonstrating its expressive capabilities:

Continuum with Lou DiBello

I've been playing keyboard and Continuum with the Lou DiBello band since summer 2011, using it to make horn sounds and to add multiple guitar harmonies from Lou's studio recordings.


In Lou's tribute to Yngwie Malmsteen, I'm using the Continuum to do dual leads with Lou. See the video on YouTube

Auld Lang Syne

In this version, I use a modified version of the big band synthesizer to do Queen-like guitar harmonies. See the video on YouTube

Handel on the Continuum

I did this multi-track version of "Alla Hornpipe" using the Continuum and Native Instruments' Reaktor.

Not-Too-Serious Moog Solos with a Band

These are from a session at Pogo Studio where I had the Continuum and CVC controlling Mark Rubel's 1968 Moog synthesizer. I had fun using the Y output to control filter cutoff and twiddling knobs on the Moog at the same time for other effects. With the Continuum, you can make a synth kinda sound like it's talking (similar to how Jimi Hendrix did it with his guitar and wah-wah pedal). The rest of the band is Mark Ginsberg on guitar, John Tubbs on bass, and Mike Powers on drums. The engineering was by Mark Rubel and his students while we were acting as guinea pigs for his recording class. Yes, that's THREE Mark's. That situation can get confusing.

(At a different guinea pig session, we had drummer Mark McKnight and there was a Mark in the class, for a total of FIVE Marks. I digress.)

Funky-Axxe Bass

Another couple of jam excerpts recorded at Pogo Studio with me using the Continuum to drive the ARP Axxe with built-in CVC, creating a bass sound. (The bass player had cancelled at the last minute). The blindingly fast response of the CVC makes it fun to do percussive things like this. Mark Ginsberg is on guitar and Gordon Kay on drums. In the second part you can hear the Axxe's Y-controlled growl modification in action.

New York Times Article

The Continuum was discussed in a New York Times article about alternative music controllers. I created a mirror page of it for when it is taken down off of the NYT site.

Indiana Jones

John Williams and Randy Kerber used the Continuum to play some of the main melodies in the score for Indiana Jones and the Kingdom of the Crystal Skull. Here is the page on the Haken Audio site with excerpts and info.

Tesla's Continuum

For the 2008 Engineering Open House at the University of Illinois, we did an outdoor concert with the Continuum driving a Tesla coil. See the video.


Here are a couple of recordings where I used the Continuum's new CVC analog interface to control the Moog modular synthesizer at Pogo Studio here in Champaign, Illinois.

All Blues

Here, I'm using the ContinuMoog ito imitate Miles Davis' trumpet on the classic jazz tune All Blues. The saxophones were also played on the Continuum, driving the software synth Reaktor via MIDI. The bass/drums background was made with the Jazz Looping Pedalboard. I used Ableton Live to do the looping.

Warm Valley

In this recording, I am using the ContinuMoog to do my best impersonation of the alto saxophone master Johnny Hodges playing on Duke Ellington's beautiful tune Warm Valley. The guitar/bass/drums background was once again made with the Jazz Looping Pedalboard.

Funk Loops

This example was part of my Continuum demo for NAMM 2006 and the Engineering Open House at the University of Illinois. All the sounds but the drums came from Native Instruments' Reaktor software running as a VST plugin inside Ableton Live for the looping. The looped parts are as follows:

Legato Saxophone

I used the Continuum's recently-improved monophonic legato to control a Reaktor saxophone sound in this version of Duke Ellington's beautiful ballad "In a Sentimental Mood". Pressure (Z) controls volume & brightness, and the front-back (Y) direction controls the depth of "growl". I created the guitar/bass/drums background with the Jazz Looping Pedalboard.

Drone & Solo

In this example, the Continuum is used in 6-voice polyphonic mode with no pitch rounding, driving a synth ensemble I created with Native Instruments' Reaktor software. In poly mode, each voice is sent on a different MIDI channel so that pitch bend information affects only one voice and polyphonic pitch bending is possible. This particular synth sound uses two square-wave oscillators per voice, with the oscillators tuned in fifths, and uses the Continuum's "Y" information to control filter cutoff. I added chorus, delay, and reverb in Cubase. One great thing you can do with the Continuum is to play justly-intonated tones above a drone sound.

Here the Continuum is used mono mode with no pitch rounding, driving my Nord Modular. The synth patch uses the Nord's"Vocal Filter" module to simulate a human voice which morphs between "Ahhh" and "Eeee" in response to the "Y" direction information. All vibrato is obtained manually by sliding the finger from left to right.

Yes, you can get funky with the Continuum. This was done with overdubs in Cubase. Everything but the drums is my Roland JD-800 played from the Continuum with no time quantization. All sounds were played with the Continuum in "Round Initial Pitches" mode.

Lead: X=Pitch Y=Filter Cutoff Z=Nothing
Clavinet: X=Pitch Y=Filter Cutoff Z=Volume
Bass: X=Pitch Y=Nothing Z=Volume

Roland Sound Canvas SC-8850

Here are a few short demos using the preset sounds on the Sound Canvas. All demos use "Round Initial Pitches" mode.

  1. Fender Rhodes - demonstrates bending, vibrato, chord sliding, brightness control, and soft attack, all achieved merely by modifying playing technique:

Reaktor Trumpet

In this mp3, the Continuum was used to control my Reaktor Big Band Synthesizer. The Z direction controls volume and brightness of a solo harmon-muted trumpet playing Gershwin's "Summertime":

With the Continuum it's easy to do very expressive solos with only one hand. In this mp3, I played the Continuum with the right hand while playing a bass line on the Chapman Stick with the left hand. This "Stick Schtick" was part of my demo at the NAMM show in January 2005. Here, the Continuum is driving a cup-muted trumpet patch on my Nord Modular. The drum sounds are loops from the Peter Erskine Living Drums sample CD with some Battery hits mixed in.

The NAMM Show

We have shown the Continuum at the winter NAMM show in Anaheim, California the last 4 years. Here are some pages about the various shows.
