Expert Sleepers Cicely

Analogue CV-controlled octave fuzz.

8 HP Eurorack module

Cicely is a fully analogue, CV-controllable octave-fuzz module inspired by the Octavia pedal. It adds an octave above suitable input tones, can overdrive the sound, and provides asymmetrical clipping and envelope following.

Features

  • Analogue octave-fuzz effect with CV control.
  • Two summed audio inputs.
  • Envelope follower with noninverted and inverted outputs.
  • Illuminated input and output jacks show positive voltage red and negative voltage blue; audio appears purple.
  • Internal JP1 and JP2 set the Mix response. Factory configuration is no jumpers: a linear dry/wet crossfade with 50% dry and 50% wet at halfway. With jumpers fitted, halfway is full dry and wet; below halfway dry stays full while wet fades, and above halfway wet stays full while dry fades.
  • Remember: when using the supplied power cable, align its red stripe with -12V at both ends.
  • No calibration is required or available.

Controls & Jacks (13)

  • Centre— Applies a DC offset to the octaving circuit for asymmetrical clipping; its 0 position is at 12 o’clock.
  • Inverted Envelope Follower Output— Inverted control-voltage envelope tracking the input signal amplitude.
  • Audio Output— Outputs the processed dry/wet octave-fuzz audio signal.
  • Audio Input 2— Second audio input; it is summed with Audio Input 1.
  • Envelope Follower Output— Noninverted control-voltage envelope tracking the input signal amplitude.
  • Audio Input 1— First audio input; it is summed with Audio Input 2.
  • Mix— Sets the balance between the input signal and octave output.
  • Centre CV Attenuator— Attenuates the Centre CV Input signal.
  • Mix CV Input— Controls the dry/wet Mix parameter; 5V spans the knob’s full range and is added to the knob setting.
  • Gain CV Input— Controls the Gain parameter; 5V spans the knob’s full range and is added to the knob setting.
  • Centre CV Input— Controls the Centre parameter; 10V spans the knob’s full range and is added to the knob setting.
  • Gain— Sets the input gain before the octaving circuit.
  • Gain CV Attenuator— Attenuates the Gain CV Input signal.
