I’m using Logic. please help i need to get sound adding scaler to an existing audio. it used to work until yesterday i didn’t change anything.

Hi @nader welcome to the forum.
If you are putting Scaler Audio on a Logic Audio track you need to arm the track if you want to hear Scaler instruments sounds on an audio track. Click on ‘I’ for Input Monitoring on the Logic Channel. You should be getting a prompt from within Scaler to do so when loading Scaler Audio on an Audio Track.
