Doepfer A-156v Quantizer Module - Vintage Edition

The A-156 module is a dual control voltage quantizer. The possible gradations on the A-156 are not limited to the usual halftone screening (ie gradation in 1 / 12V steps) but also enables other scaling such as major scale, minor scale, major chord, minor chord, root + fifth and switching sixth or seventh for the chords, i.e. the voltage values ​​at the input are only converted into discrete voltages at the output that meet the selection criteria for the permissible voltage grid (eg. minor chord with seventh).

For each quantizer the following in/outputs are available:

• Control voltage input (CV In): The input for the continuous 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 synchronised 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.
