Each routing button will illuminate brighter if connected to something, giving you an initial, at-a-glance indication of routing status.
Pressing a routing button will light only the buttons to which it can be connected. Any to which it is already connected will light brighter, indicating it’s current connections. (I am likely to change this to a more obvious indicator, e.g. pulsing.) Press again to cancel.
So to see where an input or output is connected you press its button. You may compare this with a busy patch panel where you may need to trace the cable physically.
Using RGB colouring of individual connections has many issues:
- An output may be connected to many inputs (without an extra splitter module) so it can’t necessarily have a single colour.
- Differentiating LED colours can be difficult. We all perceive light differently.
- A mass of different colours is likely to make for a difficult to comprehend system.
- The use of specific colours for inputs and outputs allows for simpler front panel labelling and UI is simpler to comprehend.
- Minimising quantity of colours allows better planning for accessibility, e.g. targeting common colour blindness.
