Mutable Instruments introduces Blades dual multimode filter Eurorack module

Mutable Instruments has announced its new Eurorack module Blades, an 18-HP dual multimode filter with continuously variable filter response, filter routing, and an overdrive stage that wavefolds.

Mutable Instruments Blades dual multimode filter

It can be used as a dual mono filter, stereo filter, dual filter in series of parallel blends with CV modulation over everything.

What sets Blades apart is that options commonly presented as multiple choices (low-pass or high-pass? serial or parallel?) are presented here as a continuum, ready to be explored at the twist of a knob or with a CV.
The filter response is continuously variable between low-pass, band-pass and high-pass, and delivers intermediate shelving responses, for more nuanced spectral coloring.
A dual crossfader circuit allows the routing between the two filters to smoothly vary from single to parallel to series.

Blades features

A CV-controlled overdrive stage precedes each of the two filters.
Overdrive response continuously adjustable between soft-clipping and 2-stage wavefolding.
Clean 2-pole (12dB/octave) state-variable design.
CV-controlled filter response, continuously variable between low-pass, band-pass and high-pass.
CV inputs with attenuverters for cutoff and resonance.
Unattenuated frequency CV input, calibrated for 1V/Oct tracking.
Clean self-oscillation across the audio range, extending into very low frequencies, with constant amplitude.
Modulating the filter response is akin to modulating the phase of the self-oscillation tone.
Continuously variable (and CV-controlled) routing from single to parallel to series.
With a signal patched into filter 2’s audio input, the routing knob and CV act as a crossfader.
Filter 2’s cutoff can be set relatively to filter 1’s cutoff.
Fully analog, based on the V2164 quad VCA chip.
Frequency knob range: 8Hz to 18kHz.
Audio input impedance: 30k.
DC-coupled audio inputs.
Filter mode CV input impedance: 50k.
Other CV inputs impedance: 100k.
All CV inputs handle audio-rate modulations.
