Hi Steve,

I can't reproduce this (but I only have one MIDI output, just tried to
output to channel 17 and got nothing.)  I'ts possible to open the same
MIDI device twice in Linux, although I don't see how your arguments
could really have done that... just as a guess, try outputs 1,3,4,5,6,7,8,9
and see if that helps?
