As it seems that some of my earlier replies disappeared because of problems
with my Yahoo account here is a copy:

We use the black knobs during exhibitions to indicate new modules and
prototypes. With the black knobs the new modules can be identified much
easier within the large A-100 systems. These knobs are used in our d3 organ
keyboard. They have exactly the same shape as the normal A-100 knobs. The
only difference is the color: black body with white line. The knobs can be
ordered as d3 spare parts to exchange the existing grey A-100 knobs. But we
will not offer the A-100 modules with black knobs.

Best wishes
