Description

A DUAL MULTIMODE FILTER…

A CV-controlled overdrive circuit capable of wavefolding.

A clean 12dB/octave multimode filter self-oscillating cleanly across the audio range.

Times two. And this could have stopped here.

FOR ALL THE IN-BETWEENS…

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.

AND MORE…

Originally thought as a complex filter, Blades turns out to be capable of much more:

  • A dual distortion with spectral color control?
  • An oscillator mixer with crossfading, wavefolding, and enough filtering to clean up the mess?
  • A voice, using one filter as an oscillator, then distorting, folding it and filtering it with the second filter?
  • A complex oscillator capable of FM, PM and AM?

An essential overdrive circuit

  • A CV-controlled overdrive stage precedes each of the two filters.
  • Overdrive response continuously adjustable between soft-clipping and 2-stage wavefolding.

Two rich multimode filters

  • 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 and constant amplitude self-oscillation across the audio range, extending into very low frequencies.
  • Modulating the filter response is akin to modulating the phase of the self-oscillation tone.

Unique routing possibilities

  • 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.
