I really love all the support this community has for each other! It's so cool making new things!

I'm trying to make a make a 6x6 check box matrix that disables further checks after 4 boxes have been checked.

I have no idea where to start, any ideas?

Basically there will be 6 inputs and 6 outputs and any input can go to any output, but only 4 of these connections can be made. And after 4, all other possibilities are disabled.

After this I hope I'll be able to help more with others Max/Msp users matrix issues.

I should also say that the inputs and outputs are for midi data, not audio. :)

it is no wonder that you dont get that to work after 2 minutes because it is actually a difficult task. even a simple "mute and solo" system can cause headache when you have to build it the first time.

for your "4 out of 6x6" system - a total of 36 registers with 2 nodes - i would tend to build the "matrix" (however) on the left side of the patch and then add a parallel structure where all user inputs/state changes are stored in a list of 36 integers.

then one can then relatively easy apply all kind of different rules for additional state changes by using a combination of simple list processing and simple arithmetics.

in case of audio, have a look at the matrix~ objects reference. edit, oh you said data. well, maybe matrix~ still gives you some ideas.

and when you dont get this or similar objects to work, you should start building a "2 out of 3x3" system first, to get the picture right.

I'm guessing you mean the matrixctrl object. For matrix routing of MIDI data, you would connect it to a router object. (For audio you would connect it to a matrix~ object.) But you'll have to keep track yourself of how many connections have been made. Here's an example.
