they have the right to see the source-code (as per the GPL).

The source code of the externals or the pd patch one?

I don't think you will be able to protect any patch that you sell....!

Maybe it's possible with compilation, PlugData is able to do this : https://plugdata.org/docs/book/CompilingPatches.html

See [vline~] help file

Another possibility is to let the abstraction take configuration message.

DO NOT split event flow without a trigger !

Is there a way to send a number from a bang using Send symbol in Bang Properties?

No, a bang send bangs.
The symbol entered is not interpreted (but $0 is replaced by the patch id).

I have a problem with a mixer.

Have you check the motor brushes?

I'm already far away…

You need a full file structure
pure-data minimal file for an empty patch is

#N canvas 122 109 450 300 12;

i.e.

#N canvas X Y W H FONT-SIZE;

And you can't connect anything without object creation.

What can I do ?

Learn how to use PD.
