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.

- 10-octave output range (0 to +10V) on each voice
- Quantizer Mode and Keyboard Mode (12 illuminated buttons act as a keyboard)
