patko:
We usually set scale by transposing to the fifth (the major scale seven half tones upper) for adding a sharp,
 and to the fourth (the major scale five half-tones upper) for adding a flat

Now I'm confused. What does Mathieu meant by "scale"? I tought it was just what number corresponds to what pitch.


Joćo:
Since there are already some projects going through in this area (e.g. pwgl or inscore), wouldn't it make sense to try to integrate with these, or try to help them, instead of reinventing the wheel?

I just tryed INScore and it looks fantastic, although I don't know yet if it can send information to Pd, how it handles microtonal information, etc. The problem I see is having that separate window to display the results. Right now I'm convinced that the ideal would be to have a display inside the same patch you are working on, a real object.

What Mathieu Bouchard did seems to be just in the right way, although it do need all that implementations you mentioned its a very very good start.
