I did not use them. The main reason is that on none of my projects
i have read back any data from the SID.
This would make the interfacing a little bit more complex, because
i would also to change the data direction of the data lines. Should
be no great problem however, but at the moment i have had no time.

When i think back to the time when the C64 was my main computer
(well, my only computer), i did experiment with pots connected to
these inputs, but the results were next to unusable. The values that i
got back changed wildly (approx. +-25 or so).

So i thought it would be a better idea to use a microcontroller that
has a built-in A/D converter. That would be easier to program, more
accurate and have the benefit of being able to add a real CV input.

But, if more people want it, i could try to add suppoprt for the pot inputs
in my freeware Monovoice OS. But it will take some time, because just
now i am very stressed at work and have little to no free time; and even
that is being used up by my girlfriend who demands some spare time, too.
(sorry she is not into synths)
