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 (J1) on the pc board that can be changed so that even quantizer 1 uses the same scale as quantizer 2. If the jumper J1 is in the lower position (factory setting) the positions of the toggle switches affect only the lower quantizer and the upper quantizer is working in the semitone mode. In the upper position of J1 the positions of the three toggle switches are also valid for the upper quantizer.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p2\"\u003e\u003cspan class=\"s1\"\u003e\u003cb\u003eFor each quantizer the following in\/outputs are available:\u003c\/b\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s2\"\u003e\u003c\/span\u003e\u003cspan class=\"s3\"\u003eControl voltage input (CV In): The input for the contiuous voltage to be quantized\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s2\"\u003e\u003c\/span\u003e\u003cspan class=\"s3\"\u003eControl voltage output (CV Out): The output of the quantized voltage\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s2\"\u003e\u003c\/span\u003e\u003cspan class=\"s3\"\u003eTrigger 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. \u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s2\"\u003e\u003c\/span\u003e\u003cspan class=\"s3\"\u003eTrigger 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.

If none of these functions are used the jack is left open.\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Doepfer","offers":[{"title":"Default Title","offer_id":42997137965245,"sku":"1016151","price":233.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/4175\/9421\/files\/DoepferA-156VVintageEditionBlack.jpg?v=1741924071","url":"https:\/\/moogaudio.com\/products\/doepfer-a-156v-vintage-edition-black","provider":"Moog Audio","version":"1.0","type":"link"}
