Erica Synths has introduced the new Black BBD, a new Eurorack module that features two BBD (bucket brigade device) lines – one short (1024 stage) and one long (4096 stage).
Features:
Full analogue design
Two BBD lines (1024 and 4096 stages)
Smooth crossfade between BBD lines
Built in LFO
CV control over Time, Feedback and Dry/Wet mix
The new BBD essentially take analog samples of a signal, pass each sample down a ‘bucket brigade’, and then convert the samples back into a continuous signal. The more steps in the device, the longer a signal can be delayed at a given quality level.
Both Black BBD stages work simultaneously and you can fade between each BBD mode, creating distinct multi-tap effect. An advanced BBD clock noise cancellation circuit is implemented, reducing unwanted BBD noise, without filtering higher frequencies of the audio signal.
