> Ok its working, I must have had some wrong parameters to the fmb3 call...

So what exactly did you do?  I thought I'd check for myself, and whatever
I do I get that single note (D in the octave above middle-C)!  I've tried
in both Csound5(where the table parameters are not optional) and
 Csound6 (where they are).

What's really odd is that fmb3.csd seems to work fine.  By default
it uses 220Hz, but if I change it to 440, say, it's fine with that, too.
I edited the file to use a score parameter for pitch, and that's fine
as well,  However, as soon as I try to get the pitch from MIDI, it
goes back to the monotonous 'D'!

Totally befuddled...!
