Joranalogue Select 2

Dual gated CV processor: select, hold, polarize, mix

6 HP Eurorack module

Select 2 is a dual gated precision control voltage processor for Eurorack, offering two independent channels of signal selection, track-and-hold, and polarizing attenuation in 6HP. It handles everything from slow CV manipulation to audio-rate processing, enabling ring modulation, waveform morphing, sequence selection, and more with a characteristically clean, high-precision analog sound.

Features

  • Two independent identical processor channels in 6HP
  • Gated signal selector: chooses between two analog inputs via gate signal
  • Track-and-hold with ultra-low leakage, maintains held voltage for several minutes
  • Gated polarizer/attenuverter: full inversion through unity gain controlled by knob
  • Unity Gate input overrides polarizer knob to force unity gain
  • Schmitt trigger gate inputs for reliable operation with slow or weak bipolar signals (2V low, 3V high threshold)
  • Left signal input normalized to +5V when unpatched (constant voltage generation)
  • Right signal input normalized to 0V when unpatched
  • Bi-color LED output indicators: blue for negative, red for positive
  • Output A normalled into Output B for mixing/offsetting when A jack is unused
  • Zero-ohm impedance-compensated outputs
  • 100 kOhm input impedance on all inputs

Controls & Jacks (22)

  • Output A
  • Output LED A Positive
  • Output LED B Positive
  • Select Gate A 1— Processed signal output from processor A. Mixes with Output B when unconnected.
  • Select Gate A 2— Gate input to select between Left (low) and Right (high) signal inputs on processor A.
  • Output B
  • Signal In A (Left)— Left signal input for processor A. Normalized to +5V reference when unconnected.
  • Hold Gate A— Gate input to freeze/hold the signal on processor A. Rising edge captures, held high maintains freeze.
  • Polarizer A— Controls amplification and inversion of signal path A. Minimum: -1 (inverted), center: 0 (muted), maximum: +1 (unity gain).
  • Polarizer B— Controls amplification and inversion of signal path B. Minimum: -1 (inverted), center: 0 (muted), maximum: +1 (unity gain).
  • Hold Gate B— Gate input to freeze/hold the signal on processor B. Rising edge captures, held high maintains freeze.
  • Signal In A Left— Left signal input for processor A. Normalized to +5V reference when unconnected.
  • Signal In A Right— Right signal input for processor A. Selected when Select Gate is high.
  • UNITY Gate A— Gate input to disable the polarizer on processor A when high (maximum output).
  • OUT A— Processed signal output from processor A. Mixes with Output B when unconnected.
  • Signal In B Left— Left signal input for processor B. Normalized to +5V reference when unconnected.
  • Signal In B Right— Right signal input for processor B. Selected when Select Gate is high.
  • SELECT Gate B— Gate input to select between Left (low) and Right (high) signal inputs on processor B.
  • UNITY Gate B— Gate input to disable the polarizer on processor B when high (maximum output).
  • OUT B— Processed signal output from processor B.
  • Output LED A— Bi-color LED: Red indicates positive output voltage on processor A.
  • Output LED B— Bi-color LED: Red indicates positive output voltage on processor B.
