Rossum Linnaeus

Linnaeus is a stereo state variable filter with Thru Zero capability.

Features:

• Ultra-wide frequency range, exponentially voltage-controllable from sub-audio to ultrasonic via precise 1V/OCT and attenuverted CV inputs.
• Thru-zero linear frequency modulation via an internal modulation oscillator and/or an external linear FM input.
• Variable linear modulation index, voltage-controllable via an attenuverted CV input.
• Resonance (Q) exponentially voltage-controllable from 0dB to greater than 60dB via 6dB/V and attenuverted CV inputs.
• Continuously variable response characteristics independently selectable for each of the two channels via individual Enable controls. Characteristics include Lowpass (12db/oct and 6db/oct), Bandpass, Highpass (12db/oct and 6db/oct), Notch, and Low and High Shelving.
• Voltage control of response characteristics via an attenuverted CV input. Individual Enable controls let you independently enable or disable CV control of response for each channel.
• An integrated modulation oscillator with continuously variable waveform from Off through Sine, Triangle, Sawtooth and Square. Its frequency can be exponentially voltage controlled via an attenuverted CV input.
• A Track control that lets the modulation oscillator precisely track the filter’s exponential frequency.
• Stereo inputs and outputs. LINNAEUS can process a stereo signal or two independent mono signals. While the two channels share the filter’s cutoff/resonant frequency, the filter response characteristics can be independently controlled for each channel.
