Joranalogue Delay 1

Split-phase analogue BBD delay for modern synthesis

12 HP Eurorack module

Delay 1 is a fully analogue bucket brigade delay (BBD) module with a split-phase topology, offering 1 to 50 ms of delay time driven by an integrated temperature-compensated high-frequency VCO. Its compander circuit, voltage-controlled feedback filter, and dual blend outputs give it a warm, characterful sound suited for chorus, flanger, echo, comb filtering, and Karplus-Strong string synthesis.

Features

  • Fully analogue bucket brigade device (BBD) delay line
  • Delay time range: 1 to 50 ms
  • Integrated temperature-compensated high-frequency voltage controlled oscillator (VCO)
  • Clock frequency exceeds 20 kHz to eliminate audible BBD clock whine
  • 1 volt per octave exponential response on Volt Per Octave TM input
  • Secondary Time Modulation input with bipolar polariser knob
  • Split-phase topology: positive (sum) and negative (difference) blend outputs
  • Integrated high-performance compander for improved fidelity across signal levels
  • Newly developed control circuit to reduce distortion and noise
  • Integrated voltage-controlled filter in feedback path (damping) with lowpass/highpass switch
  • Damping modulation input with polariser knob
  • Feedback amount knob (0 to nearly 100%) with polarity switch (sum/anti)

Controls & Jacks (27)

  • Fine— Fine-tunes the delay time for precise adjustment around the coarse setting.
  • Time Mod.— Controls the depth of delay time modulation from external CV sources.
  • Coarse— Sets the base delay time across the full range of the BBD delay line.
  • Damping— Controls high-frequency damping in the feedback path, softening repeats for warmer tones.
  • Blend— Sets the dry/wet mix between the original signal and the delayed signal.
  • Feedback— Controls the amount of delayed signal fed back into the input, increasing the number of repeats.
  • Damp. Mod.— Controls CV modulation depth of the damping parameter.
  • Blend Mod.— Controls CV modulation depth of the dry/wet blend parameter.
  • Feedb. Mod.— Controls CV modulation depth of the feedback parameter.
  • V/Oct. LED— Indicates the V/Oct tracking status.
  • Feedback LED— Indicates the feedback level status.
  • Low/High— Selects between low and high delay time ranges.
  • Anti/Sum— Selects between anti-phase and summed output modes from the split-phase BBD.
  • V/Oct. In— 1V/Oct pitch tracking input for tuning the delay time to musical intervals.
  • Time CV In— CV input for modulating the delay time.
  • Damp. Blend CV In— CV input for modulating the damping/blend parameter.
  • Pluck Feedb. CV In— CV input for the pluck feedback, used for Karplus-Strong string synthesis.
  • Low CV In— CV input for low-frequency damping control.
  • Sum CV In— CV input for the sum output level.
  • Delay Time LED— Indicates current delay time via LED brightness or blinking.
  • Clock LED— Indicates clock/tempo sync status.
  • In— Main audio input for the signal to be delayed.
  • Delay— Delay send/return jack for inserting effects into the feedback loop.
  • Out-— Anti-phase (inverted) output of the BBD delay line.
  • Out+— In-phase (non-inverted) output of the BBD delay line.
  • HF Out 1— High-frequency content output, tapped before the damping filter.
  • HF Out 2— Second high-frequency content output.
