Rossum Electro-Music Linnaeus Thru-Zero State Variable Filter Features

Rossum Electro-Music

"Make sure to listen with stereo headphones or speakers to hear LINNAEUS' filter response modulation in stereo!

Following in the tradition of Evolution and Morpheus, LINNAEUS represents yet another Dave Rossum innovation in filter technology.

LINNAEUS is a stereo state variable filter that provides the unique ability to linearly modulate its resonant frequency through zero into negative frequency, while maintaining stability. With extensive voltage control of nearly every parameter, Linnaeus lets you manipulate the filter’s natural response curve in new ways, to create both subtle and dramatic timbral effects. And with a “one-knob-per-parameter” interface, LINNAEUS inspires sonic creativity that invites (and rewards) real-time interaction.

LINNAEUS’s cutoff/resonant frequency is exponentially voltage controllable from sub-audio to ultrasonic frequencies, while its resonant gain (Q) is exponentially voltage controllable from 0dB to greater than 60dB.

LINNAEUS’s channel output response characteristics are independently and continuously variable from Lowpass, through Bandpass, Highpass and Notch, to Low and High Shelving characteristics. Voltage control of the response characteristics are independently selectable for each of the two channels.

The linear thru-zero modulation is provided by an integrated modulation oscillator and/or an External Linear FM modulation input.

The voltage-controllable modulation oscillator can track the filter’s exponential frequency or operate independently. The modulation oscillator’s output waveform is continuously variable from Off through Sine, Triangle, and Sawtooth, to Square. The modulation oscillator output is summed with the external linear FM input and applied to the modulation index VCA, which controls the linear thru-zero modulation index from zero to 8X. The modulation index is, of course, also voltage controllable.

Patching the Koma Komplex

Martin Doudoroff

"A 20 minute demo building a two voice patch with the Koma Komplex.

Note: the focus drifted on me while I recording—so frustrating!—so it gets a bit soft, but I think it’s probably still watchable."

Hydrasynth, Slim Phatty, Virus C, Pro 2, Gadget, Thor... "Terrestrials"

Brittle stR music

"A fairly minimal dub with a bottom G pedal note from the Phatty. The Pro 2 and Virus provide the chord riffs; Hydrasynth the high tuned mallets; Gadget all the percussion and sequencing; Thor does the choral pad with both LFOs modulating the formant filter. The delays are all on a dotted rhythm. The Phatty goes through a Lin 6 HX Stomp with the tape echo emulation."

"The JX-8P is a lovely sounding 8 voice analog poly synth with similar voice architecture to the JX-3P and Roland Juno series. The voice is actually quite a bit more complex than the Junos. What is gained in oscillators and modulation sources is lost in the real time control, however. There are only program buttons where numbers are typed and a single parameter slider is adjusted. This keyboard can be expanded with the Roland PG-800 programmer or connected up to an IOS app through MIDI for full access to all the controls.

This keyboard overall is in excellent condition. All of the membrane buttons and sliders function perfectly. 2-prong AC power cable included."
