I received a response (my original question copied below) to change defaults in Preferences. Where does SO hide global preferences? Doing a search in Help, there is no reference in the 2 pages returned. Standard "de facto" practice for software applications is to have global preferences under the top drop-down menu items of Files | Edit | Tools. In SO there are a few preferences under the top menu item Studio One --> Options --> Advanced.
So where do I change the default setting in Audio file tracks? I particularly want to disable the blue monitor button as deafult setting.
Is there a place to change the default of ON of the blue monitor button? This is for audio - it does not happen in MIDI tracks. It keeps on reverting to OFF, so there is an unnecessary user step to switch it ON every time one wants to listen. My work method is to listen to different takes in different tracks, and I want to quickly switch between them. But with its default as OFF, I need to first find the button, click it, and continue - very annoying.
