Eight independent free-running analogue triangle-wave LFOs in 4HP, with a global rate knob and CV input with attenuverter. Rates are spread from fastest to slowest top to bottom, and the LFOs phase organically. Designed in collaboration with Ben 'DivKid' Wilson.888

Capabilities 2

LFOlfo
Eight independent free-running analogue triangle-wave LFOs with rates spread from fastest to slowest, phasing organically due to fully analogue design.888
Modulation Sourcemodulation-source
Provides eight simultaneous LFO outputs for CV modulation, with global rate control, attenuverter, and self-patching capability for waveshaping.888

Jacks 9 (1 in / 8 out)

NameSignalVoltageDescription
Inputs (1)
Rate CV InputcvBipolar CV input summed with the Rate knob position. Positive CV can push LFO frequencies above the knob's maximum range; negative CV can fully stall all LFOs like a track and hold circuit. Scaled and/or inverted by the Rate Attenuverter.888
Outputs (8)
LFO 1 Outputcv-5V to 5VFastest LFO output; bipolar triangle wave. Top of range up to 160 Hz without external CV.888
LFO 2 Outputcv-5V to 5VSecond-fastest LFO output; bipolar triangle wave, free-running at a tuned rate below LFO 1.888
LFO 3 Outputcv-5V to 5VThird LFO output in the top-to-bottom frequency spread; bipolar triangle wave, free-running.888
LFO 4 Outputcv-5V to 5VFourth LFO output in the top-to-bottom frequency spread; bipolar triangle wave, free-running.888
LFO 5 Outputcv-5V to 5VFifth LFO output in the top-to-bottom frequency spread; bipolar triangle wave, free-running.888
LFO 6 Outputcv-5V to 5VSixth LFO output in the top-to-bottom frequency spread; bipolar triangle wave, free-running.888
LFO 7 Outputcv-5V to 5VSeventh LFO output in the top-to-bottom frequency spread; bipolar triangle wave, free-running.888
LFO 8 Outputcv-5V to 5VSlowest LFO output; bipolar triangle wave. At bottom of range, can go down to a 25-minute cycle without external CV.888

Parameters 2

NameTypeRangeBehavior
Rateknob0.000667Hz – 160HzGlobal knob that sets the frequency of all eight LFOs simultaneously. Fully clockwise places each LFO at the top of its range; fully anticlockwise at the bottom. Center position sets LFO 1 to approximately vibrato rate (3–7 Hz).888
Rate AttenuverterknobScales and/or inverts the CV signal present at the Rate CV Input before it is summed with the Rate knob position.888
