Thank you for your reply. When I create a song, I use utool in my macbook and I create one mixer preset per song (like in your oost). It works correctly. My problem is when I want to modify the mixer in the utrack. I can modify the volume, I record the new preset. When i try to launch the song, the pan is changed (but I didn’t change the pan !!). And the volume isnt the good value… like if there is another preset that confuses the utrack…
