hi list,
I attach a csd file that I elaborated for drawing
in series of png file the whole sound outline, also very long, of whole sound
processing.
Unfortunately there is't now (I suppose) a way for
saving multiple files named with progressive integer numbers
(gicount).
And I can save only last png file
processed.
Any idea?
Will be a good point on the agenda for next Csound
release?
All the best.

you can use sprintf for file name strings
