hi mark -

i'd recommend to try first whether you get the terminal example working 
in any way.  it is strange that you get a segmentation fault with it.

i have two ideas:
1. instead of the option -Ma (in the CsOptions tag), try -M0 or -M1.
2. if this does not help, try to add the option -+rtmidi=mme or 
-+rtmidi=winmm.  i have no windows, but according to the manual it 
should load another midi modul.

hope this helps -
	joachim
