Joost,

the prototype of this filter is already working. But as we have only a very
small quantity of the special diode arrays CA3019 available (~ 20 pcs only)
and could not find more of these parts a production of the "A-106-2" does
not make sense at the moment.

But we have not been lazy during the summer and I will reveal some secrets
during the next 1-2 weeks. I'm about to prepare the front panel suggestions,
block diagrams and sound examples.

Best wishes
Dieter Doepfer
