BBD Module A-188-1

"Enveloped" BBD
Control voltage for the A-188-1 is generated by the
envelope of the processed audio signal. Try positive and
negative setting of the CV2 polarity switch and different CV2
levels !
Filtered Feedback
The feedback loop is processed by an external filter. The
example shows an A-124 Wasp filter in the feedback loop.
But any low pass, high pass, band pass or notch filter (even
multiple filters like A-104 or A-127), phasers (A-101-3, A-
125) or frequency shifter (A-126) can be used.
Especially for the Karplus/Strong Synthesis (see below) a
low pass filter is useful in the feedback loop to simulate the
natural behaviour of a plugged string by damping higher
frequencies in the decay phase.
