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.
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?
