[Tom Goddard]

Hi Matt,

  There is some information about how to install Python packages with Chimera in the programming FAQ

	https://www.cgl.ucsf.edu/chimera/docs/ProgrammersGuide/faq.html#q3b

but I believe Eric here said the suggested approach to doing pip install no longer works. A more hacky approach is to simply copy site-packages/Mido (or whatever the module is called) from your system installed version into the Chimera Python site-packages (in chimera/lib/python2.7/site-packages or Chimera.app/Contents/Resources/lib/python2.7/site-packages on Mac).

I don’t know of an adequate Qt / MIDI library exists.  Really we would want PyQt5 / MIDI since all Qt in ChimeraX is done in Python.  The top Qt / MIDI hit is the QMidi library
