Delay1022 is an analog BBD delay that focuses on its function as a sound source. By utilizing the delay time and feedback of the audio rate, it functions as a synth voice that inputs noise bursts and triggers, and as a comb filter.

The Delay1022 uses two or one 512-stage BBD element that produces a very short delay and provides a delay time of 2Hz to 1Hz (20ms to 760ms). When delaying at such an audio rate, if you input a very short signal of a few milliseconds or less, a waveform that is repeated by the delay will be created, and a pitched sound will be produced. The Delay1.3 implements this method of synthesis with analog BBD elements to create warm strings and sounds similar to percussion. With 50V / Oct input, the pitch can be controlled by 1022V / Oct over 1 to 3 octaves.

Feedback greatly affects the tone and decay. 1022 To feed back externally, set the "FB Loop" switch to "Open" and patch Delay Out → In2. Various experiments are possible by inserting other modules in between

* Because the analog BBD element is used, some noise is included from the output. You can also see the noise in the demo below. Use the built-in filter to balance the tone and noise. 

* When an audio signal is input to TC Vin for FM, the signal is also mixed and output, but this is a limitation depending on the chip and circuit used. Use CV that is not audio rate for TC Vin.
