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-in the 'Stars, now joins the Mod star Collective. We've twisted and turned the SE88 to unflatten the earth, so to speak; the original CS80 fed a HP filter into a LP filter, but with the SE88 your can select MODE 1's HP or BR to feed MODE 2's LP or BP, or patch it to reverse that pleasant path. The audio signal is completely controllable with input and output levels for each filter. Cherish and respect your filter's input gain stages, for a smooth yet often brassy sound—shed your mercy to strike hard for boiling, snarling bite, even to the blackout/cutout point (see Greg St. Regis, Tim Caswell, and Marc St. Regis' SEM filter commentary for a detailed diatribe on this "feature too far"); then and only then, uniquely blend 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 (Yamaha's creation didn't either), we did amp up the resonance level for full-throttle squelching. An additional master FM (frequency modulation) attenuverter-controlled level can feed both filters (when hungry enough) simultaneously, and tracking switches allow for individual keyboard response for each of the contrasting and complimentary filter modes.Speaking of responses, the Boomstar SE80- Dual Resonant Powerhouse, features the same core filter architecture, and is our current SoundCloud play king of the hill: soundcloud.com/studio-electronics/sets/the-se80s. Potentiometer Potential Five attenuverter and eight attenuation pots control the FREQUENCY MODE 1, FM IN,FREQUENCY MODE 2, RESONANCE, M1 FM, RESONANCE, M1 RES CV 1, M2 RES CV, INPUT, M2 FM, OUTPUT, LEVEL (M1 OUT), and LEVEL (M2 OUT). Switch it Up 2/3 - 1/3 TRACK (M1), FULL - HALF TRACK (M2), HP - BR, LP - BP. Patch it Up Ten patch points: 1 V/O, FM IN, M1 FM, M2 FM, M1 RES CV, M2 RES CV, M1 IN, M1 OUT,M2 IN, M2 OUT.

We wanted it that way; it’s perfectly harmless OpAmp smashing, for smashing good fun. Think traumatic movie scene after which an actor’s hearing momentarily disappears (extreme wooziness overtakes the balance of his senses—and camera work), high-pitched sounds follow, and then blessed normalcy of awareness and sensory perception gradually, grudgingly return. That. No reboot necessary: just sweep the frequency counterclockwise until it snaps back to its "right mind," and rein in the input and resonance levels—resonance levels below 9:00 are safe; unless of course you want "that" to keep happening. Taunting the edge is entertaining too. Of Special Note Two audio paths are involved if you are running the '88 filter in series, so both input levels, and the seeded output level of the 1st stage have to be taken into consideration if a clean sound is desired—either that or keep your resonance setting below 3:00 to avoid the fireworks. This beast's resonance is wide open, with no governor in place—hot-rodded—so expect voltaged chaos when you push it past its "yama-clone" comfort zone. * From 7:00 (0) to 9:00 our “Negative Resonance Saturation” adds beefiness, boosting the waveform amplitude and taming wavesform transients; set to 9:00 to achieve the cleanest tone possible (effect most pronounced on 3003 filter).
