The interface of Presonus Studio One Professional is very simple and easy on the eyes. This application is single window based and it does not rely on the multiple windows for editing sounds. There are no additional windows but there are a few view panes that are dedicated to specific tasks. Presonus Studio One Professional supports drag and drop feature like no other application does. You can drag different virtual instruments, plugins and audio files. Once an audio file is dragged into the DAW you can automatically transform it into something out of this world by mixing some stunning effects. These features makes it very much fast in its operation.
