Is there anything that you would like to see added or handled differently than it was in Hog 2?
How would you want the patch interface to work?
If you are patching to a single note, then you would need to have 16 "universes" for your 16 channels (plus one for omni) and each universe would require 88 "addresses" for each of the notes.
There might also be cases where it would make sense to have multiple fixtures controlling the same MIDI note. I might want to have a fixture for each of my individual notes and one fixture that controls a subgroup of those notes.
