CFFI lisp interface to portmidi 2.0 adapted and actualised from https://github.com/PortMidi/pm_cl
need installation of libportmidi for OSX or Linux before running
and also install quicklisp https://www.quicklisp.org/beta/ this is the simplest way for installing CFFI
I have just tested on sbcl but this should work with all Lisp implementation with CFFI port.
Work in progress
