2 questions:

Thinking about turning my WSF into a module. It will probably get more use that way. I'm curious if anyone had problems running it at 12V? I think I remeber seeing someone who made one into a euro module and I believe they said it ran at 12V no problem but now I can't find anything on that subject.

In the module context it seems like it would be fun to be able to switch it into a lower frequency LFO mode. Can anyone suggest any mods like this?

Providing all your capacitors are rated for at least 12 volts it will work fine, it will work on up to 15 volts.

To make it go at slower speeds make C4, C7, C12 and C14 bigger, try values of between 1uF and 47uF. The filter won't pass sub audio frequencies though so to use it like an LFO you can tap the signal from the outputs of the CD40106 gates. This will give you a 0 - 12 volt output, so you'll probably want to level shift the outputs to whatever CV voltages you want.
You could also take the signal from "ODD" but this would need amplifying up to a normal CV level.
