SE88 Filter Module
!
Description
Our version of the boxy, Blade Runner-sweet and Boomstar-brash dual-mode CS80 filter, initially married
to the Omega Series Synths, and then tucked-into the 'Stars, it now joins the 3u Modstar Collective. We've
twisted and turned the SE88 to unflatten the earth, so to speak: the original CS-80 fed an HP filter into a
LP filter, but with our CS80 homage, one can select MODE 1's HP or BP to feed MODE 2's LP or BP, or
patch it to reverse path and flow. The audio signal is completely controllable with input / output levels for
each filter; respect and cherish your filter's input gain stages, for a smooth yet often brassy sound—shed
your mercy, to strike hard for boiling, snarling bite and bark, even to the blackout/cutout point; then and
only then, uniquely blend wildly divergent mode settings for the filter family values you revere.

To get things merrily modulating, each filter employs attenuverters for frequency and resonance
experimentation and decimation. While the SE88 does not self oscillate, we did amp up the resonance
level for full-throttle squelching. A master attenuverter-controlled FM (frequency modulation) level can feed
and fight both filters simultaneously, and tracking switches individualize the keyboard control response for
oftentimes contrasting, and homogeneous filter modes.
