The Doepfer A-156 QNT Eurorack Quantizer Module is a Dual Control Voltage Quantizer. Quantizers convert a continuous control voltage (within the range of 0-10V) into a stepped output voltage (in the same voltage range), meaning the quantization is controllable within that range. Ordinarily 1/12V steps are used to produce steps in semitones.
Quantizer 2 on the A-156 has some more sophisticated quantizing modes available. Switches select between Major and Minor scales, Major and Minor chords, fundamental + 5th & the addition of 6th or 7th intervals when chords are selected. The only voltages appearing at the CV output are those that comply with the selection sequence.
Quantizer 1 is always set to work in the semitone mode.
