the first is a module to write the controller value to a table or to get it's value to the controller when another destination/preset/output is being selected
Can be controlled by GPIOS controls using the CV input and button-inputs to walk through the menu
the receiveMatrix reads from the table and outputs 8 signals per module. A selector is used to select which instance it is. (this could even be manually controllable if you want, such as to switch control-values between groups of parameters)
the dispMatrix is a quick way to show which destinations are being selected.
NOTE though, that when two controls select the same destination, the destination will get the valuefrom the last module in the direction of the code. (eg most-right module)
