Hi Harin,
You can use the ParamGrabber plugin in reverse! To do this you can place the ParamGrabber plugin right of the VST or effect you want to control, then select the parameter and type in an address.
Then, you can send OSC messages from openvibe to this address and it will control the parameter. GrabberReceiver should still be somewhere in the Ableton project .
*Note that for some third party VST’s the learn function does not work (yet), if you don’t see the parameter in the list you would like to control, you can first automate the parameter, it should then become ‘visible’ for ParamGrabber.
Hope this helps!
Kind greetings,
Miro
