Overview of the EaganMatrix Expander: xCEE and iCEE
Haken Audio's Continuum EaganMatrix Expander (CEE) provides two more DSPs for sound computations, in
addition to the single DSP that is normally inside the Continuum Fingerboard. The added DSPs significantly
increase the polyphony of EaganMatrix sounds. The increased polyphony is most useful for EaganMatrix sounds
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.
The CEE also provides the ability to play different timbres using Split, or "half-advance" to another timbre using
a foot pedal when notes from the previous timbre are still held, or to do layering. While these multi-timbre
capabilities may seem important, the primary use of the CEE is to expand computation power for single timbres;
split and layering is much less important for most Continuum players than for Midi keyboard players, because
the primary way to affect timbre is changing playing style and not changing presets.
The CEE is available in two forms: Internal to the Continuum Fingerboard (iCEE), or as an external rack-
mountable unit (xCEE). The iCEE is convenient when playing gigs (less cabling!), but the xCEE is more versatile
(it can be connected to any Continuum, it provides a few additional connection possibilities, etc).
From a
sound-making standpoint, the iCEE and xCEE are identical.
In addition to this increased polyphony, the xCEE also provides a localized i2c connections to the Continuum
Voltage Converter. The xCEE can be used as a desktop device, or mounted in a standard 19 inch rack using the
optional rack ears.
The xCEE is only used in conjunction with the Continuum Fingerboard, and will not operate as a stand-alone
device.

The two LEDs on the front panel operating status of the two DSPs inside the xCEE. They will shine blue when
power is on and the xCEE is running normally. Both LEDs will flash violet if there is a problem with the
connection to the Continuum Fingerboard. LED colours will match the LED changes with the Continuum
Fingerboard in normal operation, such as during surface configuration or firmware updates.
