Reaper (v3.73) doesn`t do soft takeover if it receives:
one value from a certain CC
(ie.CC113 64)
and then
the other value for the same CC which is not the first value+-1
(ie. CC113 89)
Instead, it just jumps to 89 from 64 in this example
--------------------------------------------------------------------------------------------------------------------------------------------------------
How to replicate it:
1. Select one knob/fader on your midi controller and assign it to volume/pan of one track (don`t forget to enable soft takeover :D)
2. Move fader/knob on your midi controller. Everything should work as expected (the fader in reaper doesn`t move until reaper get`s appropriate CC`s value that corresponds to it`s position)
3. NOW, select some other bank on your midi controller which changes the CC of fader/knob in question, move it to a different position
4. Return to your previous bank and move that fader/knob...you will see instant jump in reaper without soft takeover
IT CAN ALSO BE REPLICATED THIS WAY:
Just program the same CC to two different knobs/faders on your midi controller and move them around.

I tested this with two midi controllers and the log in MidiOX doesn`t show anything strange, it`s all normal stuff:
