A state-variable filter with wide range and application. Versatile. Combining tilt and notch/boost equalization around a 2nd-order (-12dB/octave) state-variable core.
*Music and playing by Pierre-Luc Clément

*All tracks recorded to directly to line input of mixer into sound card. Only levels were adjusted, no additional equalization, no compression.
FREQ is center frequency, pitch when resonating. Range: 8Hz-6kHz
Expression input via TRS.
F CV input via 1/8" jack. V/octave response, good tracking over 5 octaves.
Plug in modulations or use as a VCO.
Q is quality factor, one over bandwidth,
resonance.
Pronounced around noon. Self-oscillates 'round 3.
Q CV input via 1/8" jack, 0-5V effective range, summed with Q control.
Try with modulations, envelopes, etc.
GAIN is bipolar,
at minimum, we are
notching the center
frequency. And at max,
boosting.
TILT is flat at noon,
shelving on either side.
From low-pass to high-pass
response.
VOL is volume. Unity gain
is around 2 o'clock.
