ADDAC System ADDAC207 Intuitive Quantizer

Four-voice intuitive pitch quantizer with a 12-button keyboard

10 HP Eurorack module

The ADDAC207 Intuitive Quantizer is a four-voice CV pitch quantizer built around a 12-button illuminated keyboard. Each voice has its own IN, OUT, Trigger and Gate Out, and can quantize independently or follow Voice 1 at a set interval for instant chords. User-definable scales, five temperaments (including Bohlen-Pierce and Just), microtonal tuning, seven modes, Moog/Buchla standards and 11 presets make it a deep yet hands-on scale machine.

Features

  • 4 independent voices of quantization, each with IN, OUT, Trigger and Gate Out
  • 10-octave output range (0 to +10V) on each voice
  • Quantizer Mode and Keyboard Mode (12 illuminated buttons act as a keyboard)
  • User-definable scales: toggle any of the 12 notes on or off
  • Major / natural-minor scale builder via Key/Octave, b/N/# and Minor/Major switches
  • Seven church modes (Ionian through Locrian) applied via Set Key
  • Five temperaments: Pure/Well, Equal, Bohlen-Pierce, Just, Exotic
  • Microtonal scales beyond 12 notes (24, 48, and in-between) via fine tuning
  • Independent per-voice fine tuning saved to non-volatile memory
  • Moog (1V/oct) and Buchla (1.2V/oct) pitch standards selectable
  • Three quantization rounding methods: Above, Below, Ignore
  • Note 2-4 interval offsets for one-CV chord generation
