@ingox Actually, I think everything I have written about passing on licenses is incorrect too as their client has them from their downloads, and all that they will copyright and license is the text files (patches) that they deliver to their client.
It is just an instruction set, like writing a macro for Microsoft Word.
The format belongs to Miller, and will be covered by the Pd license, which you must have to run the program, and which varies depending on the distribution that they use.
Maybe the Pd license for the distribution that they have used to create the patches should be included though.
But as you say, you have accessed the code of objects to create the patch...... so...
Then again, the text file could be written without Pd.
Does knowledge of an object, needed to write the text correctly, obligate the writer?
If I write letter.doc here do I have to upload the Microsoft office license to this forum?
No. But it obligates the reader if they use it.
On the monetary subject, yes for one client, but once it's "out there" you need real resources to protect your copyright.
Continued development can earn a revenue stream though.
A neighbour designs circuitry for mobile phone parts and stays in the game without patents...... through continuous development.
