Stimulation of pointers #2 to #4
Pointer actions in pointer #1 affect pointers #2 to #4 at the same time.
A delta value (deviation) from pointer #1 can be generated for pointers #2 to #4.
Maximum delta of pointers #2 to #4 to pointer #1 . . . . . . . . . . . . . . . . . . . . . . . . . .± 40 pointers

Setting a new delta value is through n x increment or n x decrement.
For n > 1, the spacing between two consecutive increment / decrement actions is 32 frames
(4 ms).
The delta for pointers #2 to #4 is retained for pointer actions in pointer #1.
