Summary

What this does: controlling volume for deck 1 or deck 2 from any interface (midi controllers, GUI, or TouchOSC) results in midi output sent back to TouchOSC to update their positions

Note: I did this without reading https://github.com/mixxxdj/mixxx/wiki/midi%20scripting and I think the midi scripting interface probably resolves the issues I had and simplifies the approach.

A google of mixxx osc turned my afternoon into this...
