Call setParameterNotifyingHost from a thread

Hi, for my test I start to change the audio plugin demo.
I only add a new thread that send periodically (every second) a setParameterNotifyingHost to change a parameter.
The parameter change in my gui but the host ( Ableton Live 8.0.1 ) doesn’t receive the notification.

Why? Can I send a notification to the host from a secondary thread?


I’d have thought it’d work just fine, but the behaviour could be host-specific…

I only try Ableton Live and I discover that all host notification function ( I try setParameterNotifyHost, updateHostDisplay, begin/endPamaterChangeGesture ) are “lost” if called by a plugin thread.
Thank’s for your reply.
