This module is no classic echo, but a delay with short delay times designed for audio rate feedback.
It can be used – triggered and/or in feedback mode – as its own synthesizer voice or for VCO-like applications (Karplus-Strong synthesis). It has a good 1V/oct. tracking over several octaves and suits well for creating drum and string-like sounds. A manually controllable lowpass filter and the feedback VCA are enhancing the sound modelling options.
Furthermore, the Delay1022 allows frequency modulation of audio signals as well as flanging and phasing effects or the realization of room ambience and spatial depth.
There is a certain amount of noise, as to be expected from analog BBD delay modules, however the Delay1022’s clear and brillant sound in combination with the manually controllable output low pass filter makes this completely tolerable.

Delay1022 Banana Versions
All CG-Products modules can be also manufactured equipped with banana sockets. Functions, technical specifications and dimensions (3U) are identical to those of the minijack version.
Two different color styles are available:
Model Klassik
Model Helene
Please note: Most CG-Products banana modules have no extra grounding socket. We recommend to use the PCV-2 for proper ground connection with external equipment!
Audio routing
(Without timebase CV)
Examples
Simple patches with other (CG Products’) modules
1. Delay1022 triggered with short impulses
The dynamic pulse output of the PEAK+HOLD (or any other impulse source) feeding the Delay1022 is a simple way to create percussive drum and string-like sounds.
2. Delay1022 triggered with noise-bursts
Better, because allowing more dynamic range and more sound options, is using short noise-bursts or another short envelope-shaped sound source to trigger the delay.
The X multiplier in this example is working as a linear VCA.
3. Delay1022 & XR22 VCO
The combination of the Delay1022 with the XR22 VCO opens up a wide variety of fascinating sounds.
XR22 VCO AM in: Rhythm machine; XR22 VCO frequency modulated with PEAK+HOLD; Delay time modulated with sequencer & 2nd VCO:
4. Delay1022 X modulated With the delay’s FB loop in inversion mode (Switch in lower position ‘inv’) and the delay’s output amplitude-modulated by itself, a 2nd ‘voice’ with interesting timbres and exponential dynamic can be produced, useful e.g. in stereo applications.
Delay In: Rhythm machine
5. Delay1022 & Pre
Embed acoustic instruments and sounds via microphone or pickup.
Delay effects, flanging, phasing etc.
Pre In: Microphone/Trumpet …Delay time modulation with sinewave
Please note: The panels of the modules are made from untreated natural aluminium, hand printed and varnished. Due to this manufacturing process, their surface may have little scratches or unregularities or may slightly differ in their color appearance.
