OK. It is working - if you get several notes it is down to the
note-detection in aubio over-detecting note onsets. I haven't done a lot
of exploring with using real musical instruments to input notes.

Right, I think I see what is going on - I was testing sequencer_fd==-1
to find out if output via timidity (or other sequencer) available, and
it seems this doesn't work. I'll try setting my own flag. The idea is
that you should get direct pcm samples sent using portaudio only if you
do not set up a sequencer to get your immediate playback.
