I am in the process of trying out Studio One Professional 4.5. Being a Logic Pro X user for many years I am already feeling that you have a real strong contender. I am using a MacBook Pro with an Apple Thunderbolt 27" Display. Whenever creating a new song or opening another I constantly have to manually enlarge the winfow until it covers the whole 27" screen. Please make it so that Studio One remembers this setting so I don't have to do this every time.
