Control messages sudddenly stop working at unexpected moments

[johannphilippe]

This is an early bug report, I still need to investigate.
I use csound6~ to propagate control signals to Max environment. It works fine until a moment (randomly, couldnt isolate the contexte yet) when control messages suddenly stop going out and are only outputted when I stop Csound.
To solve It I need to reload the object (delete, recreate). Until It happens again.
This only happens with the control output (outlet 1). The related CSD has no audio output/input.

Thanks! I wonder if this has to do with the fact that no audio is going in or out. Would you be able to check whether the problem goes away if you have audio outlets and a dummy instrument that keeps the audio rendering cycle going?

Dear Iain,
You strategy worked perfectly. To make sure audio was still running, I routed an always on oscillator to a dummy audio output, and control messages kept working. Concert was a success.

Thanks !

Good to know! I will add something to the help file indicating that audio blocks must run for the next release.
