The Delay1022 is no classic echo, but a delay designed for audio rate feedback and sound sculpturing (Karplus-Strong). The 1V/oct. tracking and a 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 brillant sound in combination with the manually controllable output low pass filter makes this completely tolerable.

Examples

Simple patches with other (CG Products’) modules

Delay1022 impulse triggered

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.

Delay1022 with noise bursts

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:

Delay1022 X modulated

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.

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.
