An online wiki: http://wiki.laptop.org/go/CSound#MIDI_playback recommends I use a compilation option -F for midi file playback. Where do I put this option--in the instrument or in the score? Also, since this is just to describe note values and duration, will I still have problems with Csound not recognizing midi message 0xfd? Thank you for your time.
