BBD Module A-188-2

DOEPFER

The feedback can be increased up to self-oscillation. In

contrast to other feedbacks (e.g. filters or phasers) the result

in the self-oscillation state depends upon the "audio history"

(i.e. the contents of the BBD when the self-oscillation is

triggered). The reason is that there is not only one possible

stable self-resonant state for the BBD. Any cyclic waveform

"stored" in the BBD is able to resonate provided that the

feedback maintains the waveform. One can try this out e.g.

with different audio signals (e.g. digital noise and VCO

sawtooth) as audio input before self-oscillation is triggered.

A special feedback can be obtained if one of the sub-mixer

outputs is used for the feedback function. In this case for

each tap the positive or negative feedback share can be

adjusted. This leads to multiple peaks and/or notches in the

frequency response of the module.
