thank you Victor! Very useful!
Below there's the file correct with your help
(file name path should be replaced for testing, of course).
But there's some line unexpected in second png file
processed.
Maybe is there some critical question on management
of images with csound?

Sorry, can't help you there, I don't know anything about png files.

Hi Andrea, I tested the csd and it seems to run (sort of) fine here. I don't fully understand how it should exit, and it hangs (just stays open) after producing 3 images. I needed to terminate csound with Ctrl+C The images are black with some white downward exponential slopes The console print is SECTION 1: new alloc for instr 1: ftable 1: ftable 1: 16384 points, scalemax 1.000 _ . .
