Demux Phaser
Description/Usage
8hp
This module is a ‘digitally’ controlled phaser. Instead of using a CV to control the phasing, it requires one to three gate signals (anything crossing 1V will work). The core of the circuit is inspired by the schematic in the article ‘Digitaal Gestuurde Phasing’ in Elektuur 7-8 1979.
The main changes, from the Elektuur circuit, are using DG408 switching ICs, rather than 4051 chips, left out the logic and clocking circuitry (plenty of Eurorack modules can do all that), individual stage outputs on the panel and a feedback path from stage 6 via the switch pin on IN 2 and an attenuverter.
Feeding any of the stage outputs into IN 2 will switch out stage 6 and alter the feedback effects. You may like to process one of the stage outs in some other module, say a delay, wavefolder, VCF or VCA, feed it back to IN 2, just to see what happens.
The MIX pot mixes the stage 6 output with the input signal, 0 is fully wet (stage 6), 10 is dry (input).
