Just wondering: how do you get the data from DistoX into Therion? I was not
very successful since the *.top files are not easy to parse, and apparently
not ducumented. What is exported for Therion is just a sketch, but it would be
nice to have *.th files produeced from *.top files directly.

I had contacted Beat about that, but never got an answer.

So my question are:
o How do you export DistoX data to Therion?
o Does anybody have a documentation on the *.top format, or source code to
  read it?

Thanks, Martin
