Here is the modified code to compile in SVN version of CLAM, using
SendFloatToInControl(), plus a SConstruct...
Best regards,
Natanael.

Please note I'm using verison 1.2 (on Hardy). However, I had
occasionally the same problem on my laptop, where 1.3 is installed

Jaunty)
I see that your code uses GetInControl("...").DoControl(...) which means
that you use a clam version prior to the TypedControls refactoring (I
don't remember if that made into 1.3 or not).
Since we are trying to fix a bug I recommend you to use the last
subversion revision (we keep try to keep it stable)
Just use this helper function in Processing.hxx
/**
* Tries to send a float to an inaccessible InControl, this is kept for
compatibility
* This function uses the InControl's name to identify it.
* @pre The type of the control is Float
*/
void SendFloatToInControl(Processing & receiver, const std::string &
inControlName, float value);
We have just reproduced your results here! and i'm very surprised of
that, because NE only adds a user interface to the jack process, nothing
else. We'll investigate further and get back to you.
Thanks for your feedback

ps: Yes the clam ml is down, to be fixed (and moved to another hosting).
However clam-devel is the relevant list.
