Olivella Modular Duplex

Olivella Modular Duplex

DÚPLEX is a dual solid-state low pass gate, featuring no vactrols but sounding exactly like the real thing. Each channel has: voltage control over decay, level and offset, a PING input that converts any signal into a suitable trigger for the circuit (running all the way into audio rates!), a 1-pole or 2-pole filter response, a switchable CLICK amount and an envelope output. The module is fully DC-coupled, so it can also process CV as well as audio.

Features

Complex envelope-based vactrol-free core
DECAY knob and CV input w/attenuverter per channel
LEVEL knob and CV input w/attenuverter per channel
PING inputs that convert almost any signal into a suitable trigger for the core
-6dB/oct or -12dB/oct filtering response switch per channel
CLICK softens (or not) the initial transient of the sound
ENV outputs per channel
MIX output
