I don't think you need to do this (anymore). Control objects work fine without DSP being turned on in the subprocess, like the documentation says.

@iftah, some more ideas:

* make sure DSP is turned on in the parent process (even if the subprocess doesn't process audio)
* make that the subprocess could really load the patch (verify with the GUI)
* in the subprocess, send a message to [stdout] with [loadbang] and check if you receive it in the parent process
* send a message to the subprocess and check if it is properly received, e.g. by sending it back to [stdout]
