[CM] grace midi ubuntu [timidity] ...

[Heinrich Taube]

i think in linux you have to do someting manually in qjackctrl    
before you try to open the port.
also try using the menu rather than the lisp calls to make sure that  
the basic mechanism is working (or not).
if you get it working let me know how, i cant find my notes on how to  
get midi ports working in ubuntu.
