copy a matrix into another one, with offset

January 11, 2013 | 2:53 am

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
strangely.

Here is the machine:

– Pasted Max Patch, click to expand. –

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..
