Will you be releasing anything else in conjunction with the new format, like a toolbox for handling the files (e.g. librns), or just what’s built into Renoise?
Speaking of which, are there any specs or reference materials on how the current binary format is put together?
about binary specs: no, there are no public binary specs.
the XML format will be (of course) public and documented, but I can’t say anything about a librns
We promise you that as soon as we know that (almost) nothing will be changed (or at least no dramatic changes) for the upcoming release, we shall publish the xml format and hopefully this might be long enough before the actual release so 3rd party devs could examine and develope tools.
