Get those continuous voltage changes turned into steps with the Doepfer A-156 Dual Quantizer module for Eurorack systems!

  • Quantiser module for Eurorack
  • Turns a continuous voltage change into a stepped one
  • Two onboard quantizer modules
  • Quantizer module 2 offers more sophisticated scale-based quantization modes
  • Width: 8HP
  • Current draw: 50 mA

The Doepfer A-156 is a Dual Control Voltage Quantizer.

A quantizer converts a continuous control voltage in the range 0...+10V into a stepped output voltage in the same voltage range (i.e. only certain voltages occur).

Normally 1/12 V steps are used to obtain semitone steps. Quantizer 2 of the Doepfer A-156 allows has more sophisticated quantizing modes like major scale (i.e. only voltages corresponding to the major scale), minor scale, major chord, minor chord, fundamental+fifth and addition of seventh or sixth when chords are selected.

Only those voltages appear at the CV output which comply with the selection rule (e.g. minor chord with seventh). The mode setting of quantizer 2 is done with 3 switches (1-0-1 type with middle position).

From the factory quantizer 1 is working in the semitone mode. But there is a jumper on the pc board that can be changed so that even quantizer 1 uses the same scale as quantizer 2.

    The Make Noise Brains is an expansion module which allows their Pressure Points module to behave like a 'normal' step sequencer

    • Voltage Control over Direction, RUN/ Stop and ReSeT
    • Pressure Points provides data input to BRAINS in the form of touch selectable ReSeT and Hold stages and patchable ReSeT Pulses per stage
    • Pressure Points provides the tuned voltages per stage
    • The Touch-GATE OUT produces a Gate HIGH signal whenever a Pressure Points is touched
    • Maximum number of Pressure Points that may be connected to a BRAINS is two
    • Ships with all cables needed for expansion of one or two Pressure Points
    • Pairs only with Make Noise Pressure Points modules
    • Width: 4hp
    • Max Depth: 36mm
