Doepfer A-188-1D B-Stock

Bucket Brigade Device Module

Bucket brigade device module are used to delay audio signals before digital delays can diminish the effects produced by the BBD. BBDs have a number of very unique advantages (or disadvantages – depending on one's point of view) over their digital counterparts, which result from the specific characteristics of BBDs. BBD circuits can be regarded as a chain of sample-and-hold (S&H) units, which pass their voltages on to the next S&H in the chain at each clock pulse.

In either case, the sound produced by the A-188-1 module is quite special. Common applications include: Flanger, chorus, analogue delay or Karplus/Strong synthesis. However, as the A-188-1 has many highly unique features (voltage-controlled clock rate / delay time with an extremely wide range, polarity switches for CV inputs, feedback and BBD-Out / Mix, clock and CV outputs from the high-speed VCO, BBD clock input, feedback stage, feedback up to self-oscillation), the module can be used to create many unusual applications (such as, controlled by ADSR, an envelope, randomisation or a sequencer (with a positive or negative effect).
