Overview - Rossum LINNAEUS Operation Manual

3. Overview

What is Linnaeus?
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 subaudio 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. Voltage control of the
response characteristics can be
independently selected for each
of the two channels.
