    I have a 105x10 LED matrix in 32 colors.

    The Control / Driver for them is in the Matrix format mentioned above but, the actual LED layout is one long sequential line of 1050 LED's!

    My need is to be able to turn the LED's on and off, one or many on at a time but one color at a time(the LED's of the same color maybe or maybe not sequentially next to each other).
    A practical example would be in pixel art where you need to show one line of the pattern that is made of 32 colors but you will be turning on all the red LED's sequentially for example pertaining to that row first before turning on the yellows etc. in the same manor.

    I am thinking of cascading 132 x 74595 and loading for example all the Reds first and then resetting and loading all the Yellows next etc.

    Is this about the right direction pleas? Do I need PIPO or PISO?

    thanks for all your help and advice.
