Q171 Quantizer Bank

The Q171 Quantizer accepts an input voltage and produces an output voltage that is locked into a selected group of notes (semitones, scale, chord, etc.) maintaining correct intervals between steps. The quantizer's primary use is to simplify tuning of an analog sequencer, but there are many other musical applications. Any voltage source can be processed by the quantizer including envelope generators, oscillators, noise sources, etc. The Q171 can be synchronized with external events and operated as a programmable Sample & Hold using the Gate Inputs. A Gate Output signal occurs whenever a new quantized output signal level is produced. Three independent channels are provided. Channels produce one of the valid semitone notes (12-notes per-octave) unless an alternate group of notes is selected using the option switches. These option switches narrow the possible outputs to further simplify tuning. Possible note groups include Semitones; Major, Minor, Augmented, Diminished versions of scales; Triad chords; and Root+5th.
