Activation of modular synth on Play

I would like to incorporate a modular synth patch in my session. I want to use Cardinal Synth, but I want the patch to be activated only when I press the Play button in Ardour. I am referring to a patch that does not use a MIDI controller, but rather relies on a continuous clock, sequencers, etc.
I tried to include the Cardinal plugin in a dedicated track, but it keeps on playing whether playback is on or not.
My question is: how do I get a “Play”/“Stop” signal from Ardour’s transport control to the modular synth?
Thank you.

Add the “Host Time” module to your patch. Use the “Playing” output.

Thank you Paul - I will try it.
Talk about fast responses - I barely hit “Send”… :smiley:
