How to draw pictures with 30 dots

i am new to touch designer and i have a really specific task that i want to use it for.

i want to draw simple pictures with dots, using a maximum number of 30 dots. the art that i’m drawing with dots will look sort of like the style/complexity of one tattoo in this picture (not all of them at once):

i would like each dot (xy coordinate) to have it’s own corresponding x and y signal output that i can turn into DC and output from my audio interface as voltage. probably linking several audio interfaces together to achieve number of outputs required for the project

What do you mean by “dots” in this context?

hi thanks for writing. i actually wrote a better description of this in this thread:
