Doepfer A-156 Dual Quantizer

Doepfer A-156 Dual Quantizer brings equally tempered musicality into your eurorack system, which otherwise would be hard to achieve by your own ears and knob settings. That means that it turns any slowly changing (i.e. low-frequency) signal into a V/octave-based output. With seperate trigger inputs, you can create transpositions in your melodies too.

Doepfer A-156 Dual Quantizer brings equally tempered musicality into your eurorack system, which otherwise would be hard to achieve by your own ears and knob settings. That means that it turns any slowly changing (i.e. low-frequency) signal into a V/octave-based output. With seperate trigger inputs, you can create transpositions in your melodies too.


Doepfer A-156 Dual Quantizer is a Dual Control Voltage Quantizer. A quantizer converts a continous 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 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.

For each quantizer the following in/outputs are available:

Control voltage input (CV In): The input for the contiuous voltage to be quantized
Control voltage output (CV Out): The output of the quantized voltage
Trigger input (Trig.In): If this jack is left open the quantizer is working permanently. If a rectangle voltage is applied quantisation happens only at the rising edge of the signal (e.g. from an LFO or MIDI-to-Sync interface). Thus the quantizing can be synchronized with other events.
Trigger output (Trig.Out): Whenever a quantisation happens (i.e. a new voltage is generated at the CV Out) a positive pulse occurs at this output. It may be used to trigger an envelope generator (ADSR) or for triggering other modules (sequential switch A-151, trigger divider/sequencer A-160/161, trigger delay A-162, ...). If none of these functions are used the jack is left open.
On top of that the A-156 is provided with a common transpose CV input having an additive effect on both quantizers. This input is quantized in semitone steps. A typical application is the transposition of a sequence generated by the A-155 by a second control voltage (e.g. coming from the MIDI-CV interface A-190).


Typical applications:

Quantizing the CV sequence generated by an A-155 (semitone, onyl major scale, only minor scale and so on) quantizing the voltage coming from the Trautonium Manual / Ribbon Controller A-198, Theremin A-178 to get accurate semitones or major/minor scale tones
arpeggio-like effects with LFO, random, noise, envelope generators as CV sources (for negative or symmetrical voltages an offset must be added, e.g. with the offset/attenuator module A-129-3, to obtain positive voltages for the A-156 input).
