How do I set up a knob with fixed snap-to points on a logorithmic scale?

[adamvs]

My question is pretty simple, but after rooting around in the knob/gauge proteries I can't seem to figure out how to do what I'd like:

I would like a simple knob type control  with 4 possible values: 0.0125,0.125,1.25,12.5

I'd like them evenly spaced and I want the knob to only snap to one of these four values

I can at least get it to the point of having four values on there by placing arbitrary markers (scale->add marker), but I can't figure out how to get it to snap to these, or even if this is the bets way to go about it.

Thanks!

See attached LV86 example. Open the properties dialog of the knob for more info about its configuration.
