Thank you. That was more helpful.

Honestly, this is not "nice", it is just boring. Which is not your
fault: you could not hope to achieve in a summer what eludes years-long
PhD theses in musicology and artificial intelligence. The project was as
it is, and you seem to have more or less succeeded to implement it.
Variations of rhythm would have been nice, though.

But the fact remains that this is of no practical use. It is of no use
to just listen to and enjoy, and since it uses an external library it is
of no use for testing. (This project seems to be based on an old
proposal of mine, with the goal to have a varied and somewhat realistic
source for audio testing. But testing requires we trust the source is
bit-exact.)

Since you know the API best, could you say in a few words how hard it
would be to get rid of fluidsynth and use an internal synthesizer
instead?

But in any case, your most urgent matter at hand is this:

> > $ ./ffmpeg_g -lavfi atone /tmp/atone.ogg
...
> > zsh: segmentation fault  ./ffmpeg_g -lavfi atone /tmp/atone.ogg

Because we definitely cannot accept a patch that segfaults like that.
