CONTINUUM EaganMatrix Expander (CEE)

Internal DSP expansion that triples the processing power of the EaganMatrix. This is available for the Half-size and Full-size Continuum Fingerboard only, not for the ContinuuMini.

The Continuum Fingerboard contains a single Digital Signal Processor (DSP), which computes the internal sounds. Haken Audio’s Continuum EaganMatrix Expander (CEE) provides two more DSPs for sound computations, thereby tripling the polyphony of EaganMatrix presets. This increased polyphony is especially useful for EaganMatrix presets that require polyphony greater than the number of fingers simultaneously touching the surface, such as percussive sounds with releases that continue long after the finger is lifted from the playing surface.


In addition to polyphony expansion for a single preset, the CEE also provides the ability to have two or three different presets loaded simultaneously. The presets may be played with Split, or with Sequential advance to another preset (using a foot pedal) when notes from the previous preset are still held, or with Layering. While these multi-preset capabilities may seem important, the primary use of the CEE is to expand computation power for single preset; split and layering is much less important for most Continuum players than for Midi keyboard players, because the primary way to affect timbre on the Continuum is by changing playing style and not by changing presets.

EXTERNAL EaganMatrix Expander (xCEE)


An external rack-mountable DSP expander that triples the processing power of the EaganMatrix, and includes connection to CVC (if present). The xCEE is available for the Half-size and Full-size Continuum Fingerboard only, not for the ContinuuMini. Haken Audio still has a few xCEE available for purchase, but is no longer manufacturing them. Most Continuum players prefer the internal version described above.
