ofxMidi updates

Hi,
I love this addon, but I'm trying to run it in a C++11 64bit compilation of openFrameworks and I don't know what I need to do for it to happen.
As oF 0.9 introduces C++11 and 64bits I thought it'd be relevant for more people then just me.
I can help to add this feature, but I'd need tips as to where to start.

I'm using a 2011 macbook pro with OS X10.10.3 (going to update it today) and it seems to be a mac-only error :
