ahh i believe i see what your saying and how that could work, i think, not 100% sure i see all the way but i'll look some more on it.?
if i see correctly i need to explain the scenario fully. If one transmitter is physically labeled Input one then the end user connects that to say input 9 of the Matrix on the Touchpanel i want to be able to enable a button that says input 1. when this is pressed it routes the transmitter through correctly whether the transmitter is on input 9 of the matrix or ends up on 12 of the matrix.
if that is clear you think the solution your proposing can do this? if so i may need you to walk me through it again please.
