Effects Switching system development

I have done some more work on my Effects Switching system that I'm developing. I have taken a whole bunch of things into consideration. I've developed a modular platform that can be added onto as needed.
This way I can develop a new module that hooks into the same BUS and can do different things. I have since learnt that MIDI control is relativity simple (so to speak) on the arduino platform. It's only in design stage at the moment. I still have more simple switching systems that I will build this year to use up current PCBs I have (4-8 channel systems). With my new Modular system I can have some pretty crazy amounts of inputs and outputs.
Inputs switches (stomp or tactile for programming) - 56 Total
Expansion modules - 1000 Total
          Relay Module - 4 x True Bypass Channel (LED on each)
                                   4 x Independent LEDs
                                   Can be used as 4 independent relays for amp switching
          Tails module - 4 x Buffered Tails channels (LED on each)
          4 x Independent LEDs
           ((More modules under development))
MIDI send, receive, through
LCD screen 4 or 2 line dot matrix screen


This is just the bare bones of the switching system. With the use of the modules anything can be controlled.... well that's the plan anyway.
