thanks! and no problem :) How was the conference? Sorry to miss it  
this year (there was quite a but going on that looked good).

I noticed the API warnings and as I looked through more of the code, I  
was starting to wonder if those were the problem (since I imagined any  
architecture / endianness things would be taken care of by the  
compiler???). I'll take a little more of a look later. I actually  
don't need any GUI at all for the project I am working on, and the  
move to QT makes quite a bit of sense.

I'll write with questions later. I was thinking about just trying to  
use one of the more generic C/C++ graphics libraries to export simply  
to jpeg, gif or tiff (and avoiding the whole OSX only libraries), but  
didn't get too far with that when other matters became a little more  
pressing!

Are you familiar with SuperCollider? If you are (or if you have it  
installed), let me know and I can send you some sample code. A number  
of pieces on my website were done by generating GUIDO algorithmically  
from SuperCollider -> NoteAbility, then tweaking graphics. If you  
would like to see some of those, they are here:

Both Anacrusis and Palimpsest were GUIDO generated. There will be a  
couple more posted there later this week (the site needs updating!)

Thanks for the reply.

best,

Josh
