Hi I'm using protools and have set up a send bus from my trigger and keyed the pro q on the track i want to sidechain.
I am receiving sidechain spectrum view but the sidechain button is not showing in the threshold popout, so i can't assign the input.
What am i missing here?
Many thanks for your time.

Are you using the latest version? The functionality was only added later, so it may be worth a try downloading the latest version.

Bram. Thanks you legend, that was it. I only bought it at the start of the year, didn't realise it was such a new function.
