Share 'Triggering solution refresh from a custom component?'

I'm trying to write a set of custom components, in C#, that will allow someone to control grasshopper through a MIDI controler. For example I have a Korg Nano Kontrol:   I was able to get a prototype of controlling Grasshopper with MIDI working earlier, but honestly what I had setup was kind of a hack. So now I'm trying to create a set of true custom Midi Controller components that would be easy…
