Can you post some code? If you want to keep it secret, you could also send it to sdk_support or via PM.
I'd also be interested in the Get/SetDParameter() implementation, that broke the keyframes.

tell me which portions you want, as I guess GeUserArea and CustomDataType portions are not needed here.
I will post more code soon if needed.

Hi Mohamed,
terribly sorry, this took so long. I have to admit, I went down the wrong road all the way to the end, before I realized, I took the wrong branch. My fault!
In Germany we say: Shooting yourself into your own knee. 
Also I have no clean example code to post here, yet. But before entering my weekend, I still wanted to provide you some infos.
Basically you were right in the beginning with your assumption, that it's similar to handling a vector. Unfortunately there's no macro nor any defines for the CUSTOMGUI_SPLINE.
Here's how you do it manually:
After checking, that your spline got addressed (id[0].id == your spline id), you need to check if id[1].id.
If it is zero, t_data is of type CUSTOMDATATYPE_SPLINE. So you get a complete updated spline.
If it is unequal zero, then you need to handle the "subchannels".
If the id[1].id is greater 10000, you can use this:
Int32 knotIdx = (id[1].id - 11100) / 100;
Int32 partIdx = id[1].id - (11100 + (knotIdx * 100));
knotIdx can be used directly with GetKnot().
partIdx decodes as follows:
0: position x
1: position y
2: left tangent x
3: left tangent y
4: right tangent x
5: right tangent y
I hope this helps. On Monday I will probably post some more code. Also there are more subchannels (that's why > 10000).

great
about decoding partIdx, is this bit masks? (1 << 0, 1 << 1, ...) or just Int32 values?
also waiting for all subchannels, the same for Gradient "as it is very similar, it has its post though"
thanks for the help Andreas.

Hi Mohamed,
no, it's not a bit mask, just integer. And the data you get is of type Float.

Hi Andreas,
I tried to fix the spline Get/SetDParameter, but this is a nightmare...
there are a lot of unknown description ids "not shown by show sub-channels"
any idea how to iterate over all sub channels and set/get as required?
here is what I did so far, works fine to some extent "tangents and point count are making a problem, if you animate point count the behavior is undefined"
