Description
Unlock the full potential of your modular synth setup with the Doepfer A-156 QNT Dual Quantizer. This versatile module transforms continuous control voltages into precisely stepped musical scales, offering a dynamic range of creative possibilities. Whether you're crafting complex arpeggios or adding harmonic depth to your compositions, the A-156 delivers advanced quantization options including major/minor scales and chords, along with the addition of sixths and sevenths. Ideal for use with a variety of continuous sources—like theremins, ribbon controllers, or light-to-CV modules—this dual quantizer ensures your output is always musical and on-point.
For even more nuanced control, the transpose CV input allows for real-time modulations, quantizing in semitone steps to affect both quantizers simultaneously. While Quantizer 1 offers flexible scale and chord settings, Quantizer 2 simplifies things with a fixed semitone grid, making it perfect for more straightforward applications. Whether you're a seasoned synthesist or just getting started with modular gear, the Doepfer A-156 is a powerful tool to elevate your sound design.
Key Features:
- Dual quantizer for Eurorack modular synthesizers
- Converts continuous control voltage (0-10V) into stepped output voltage
- Quantizer 1: adjustable scales and chords (major/minor, fundamental fifth, sixths, sevenths)
- Quantizer 2: fixed to semitone grid
- Transpose input quantized in semitone steps affects both quantizers
- Perfect for analog sequencers, ribbon controllers, theremins, and more
- 8 HP width, 55mm depth
- Power consumption: +50mA (+12V), -10mA (-12V)

Mods and upgrades
-
Consider replacing space-consuming modules like the Jomox ModFM to optimize rack space for additional utility and modulation modules.
Source -
Some users consider replacing the pots on the Blue Lantern Duo-Quant to improve usability, suggesting potential DIY modifications for enhanced performance.
Source
Use cases and applications
-
For building a 4-note polyphonic synth, identical VCOs, VCFs, a quad VCA/mixer, and a quad envelope generator are needed, which is challenging in 112HP.
Source -
Quantizers can transform odd voltage sources into musical intervals, enhancing modulation with stepped outputs from continuous signals like LFOs or envelopes.
