Delay Memory Brigade - General Questions
BBD stands for "bucket brigade device".
The name comes from the world of firefighting, where firefighters would pass buckets of water from one person to another to extinguish a fire.
Similarly, a BBD is a type of circuit that passes an analog signal through a series of capacitors to achieve delayed echoes.
Each capacitor can be thought of as a “bucket”. Once it fills up, signal passes to the next capacitor introducing a delay to the original signal.
Input levelAdjusts the volume of the input signal. High values will saturate the preamp, adding color to the signal.
BBD SizeSpecifies the length of the BBD delay buffer. This setting modify the range of the Delay Time knobs. Note that while in Sync mode, the BBD setting will limit the Delay Time values to 40.96 & 409.6ms (Min/Max) in Deluxe Mode and to 110 & 1100ms (Min/Max) in 1100 Mode.
Left/Right DelayAdjusts the time between each echo. Each channel speed can be adjusted independently, linked together and synced to the DAW tempo.
FeedbackControls the regeneration of the echoes, going from a single repeat to self oscillation on highest values.
Stereo offsetStereo Offset induces a timing offset between the two channels, creating a spacey stereo effect.
Stereo WidthStereo Width accentuates or alleviates the stereo width of the signal sides.
Chorus/Vibrato AmountSets the amount of chorus or vibrato effect that will be applied to the delayed signal.
Echo LevelAdjusts the volume of the processed delay signal.
BlendSets the ratio of processed (wet) to unprocessed (dry) sound output from the plug-in.
Delay ModeDetermines how the input signal is processed.
It can either be Stereo, Ping-Pong or Mid/Side.
