Matrix sequencer rows ok, columns not ok

Hi

Attached is a patch I am building using a matrix as a sort of sequencer using jit.peek to read through the rows to play sounds using cellular automata
(looks better in presentation mode)

The idea is built around a patch I was originally sent by Scatlogic on these forums.

I would like to have it set up so that the columns also provide a sound source

If i try to set up the jit.peek subpatch using the same idea as I have for the 'rows' and using it for the 'columns' I have no luck

Can anyone tell me where Im going wrong
(I have jit.peek's dim 0 receiving sound generator data and the dim 1 recieving a sig~n (1 for each row (1-64)) argument so how would I edit this to achieve sounds playable per row if the sig~ is already connected?)
