The first Karplus/Strong examples have been added to the preliminary page of
the BBD module (www.doepfer.de/A100_BBD.htm).
I'm still waiting for the answer of the BBD manufacturer if even 1024 stage
BBD's are available. If it is available we may put both BBDs on the module
(2 outputs available that can be used to mix together with the original
signal and two different feedback pathes, both with positive/negative
control). Thank's Ingo for this idea - even if the module will become a bit
more expensive (~ Euro 150 instead of ~ 100, only a rough estimate !).

Best wishes
