copy a matrix into another one, with offset

    hi there,
    a final output matrix, displaying blank screen at the beginning
    another matrix with content changing each x seconds.
    both same width, but the second one is 1/8 height of the first one.
    The big one has to be filled progressively, each x seconds, by the content of the small one, using offset
    in a cycle, after x second, the first 1/8 is filled.
    then after x, the second 1/8 (the first 1/8 still contains the previous stuff)
    etc till the end where all become blank again
    struggling with @usedstdim and the other companions in tutorial 16 and the content of the smallest is always copied at the bottom
    Here is the machine:
    any leads would totally unstick me :)

      I guess the one fitting the most is the final one (in the last post) but I still understand the underlying idea :-/
      Using matrix operation like +, if I could store the new bands in a total black (empty) matrix, I could sum this one each time with the last one and accumulate the values..
