Studio One needs to improve in this department. No way we can have a DAW eating up to 50% of processing when in background. Yes, you can turn "release audio in background" on but that you cannot continue to listen when you switch to another program.
Take Reaper as an example. If the song is playing it won't stop if I open Chrome e.g. but if there's nothing playing processor use will go down to literally almost nothing.
Please. This is the one thing that always makes me rethinking if using studio one or not.
