MIDI is essential to realtime Csound.

Portmidi has long been the MIDI standard in Csound. I note it's on the list 
you cite.

Any reason it can't be used?

OTOH, alsa was used (on the XO-1) for rtmidi. Can't it continue?

(My activities are meant both for the XO-1 and SoaS; so as much 
consistency/continuity as possible would be helpful to me. [The XO-1 used 
alsa for both audio and midi.] Otherwise, I think separate versions will be 
required, unfortunately.)
