Trouble with Min/Max/Default on set driven keys

Animator getting my rigging feet wet following some basic tutorials - did a fair bit of googling, found others with the issue but no solution, many apologies if this is covered somewhere obvious.

Working in Maya 2010 64 Bit. When I create attributes and set driven keys I am unable to see any in-betweens in the rotation, e.g.:

Toe_Roll has a min -10 (-30 x rot), default 0, max 10 (30 x rot)

When I set Toe_Roll to 10, -10, or 0 the joints make the appropriate rotation - but when middle mouse scrolling from -10 to 10, I see no in-betweens, it simply pops between the 3 different rotations.

Tried setting some keys on the controller and splining in the graph editor - no changes along the curve, simply pops once it reaches -10, 0, or 10. (not sure if it matters, but weirdly noticed that the attributes were not snapping to frame times, despite that being default - and further refused when highlighting them individually and edit-> snap)

Have started over twice now, encounter the same problem each time. Hope it all makes sense, I suspect I'm overlooking something simple. Any help would be greatly appreciated!

That's weird. Have you tried entering values by hand? Well, if I can have a look at your scene would be easier to know why this happen.

Hey, thanks for the reply! Typing by hand has the same results as middle mouse scrolling, only works on the 3 designated values. Applies to all of the attributes I've added, highlighted "Ball Lift" just for clarity.

Select your 'lft_ballLift_GRP', open graph editor and check your SDK anim graph tangent.
They're all stepped. Change them to linear and your problems are gone.

*smacks forehead*

Didn't even think about the groups I was setting keys on to make them driven. Now I understand what they were talking about on google....
