Modular
Delay1022
Analog BBD delay
1. Introduction
This module is no classic echo, but a delay designed for audio rate feedback and
sound sculpturing. The 1V/oct. tracking and feedback CV input makes it suitable
for many VCO-like applications, for creating drum and string -like sounds and/or
for room ambience. There is a certain amount of noise, as to be expected from analog BBD delay
modules, however the Delay1022's clear and brilliant sound in combination with the manually
controllable output low pass filter makes this completely tolerable.
2. Features
– Delay times from 2.5 ms to 50ms (without T CVin)
