Basically it is a timesaver. But sometimes when i am busy with my mouse, i forget i have the CC121. Because with the mouse scrollwheel you can do the same as with the Knob of the CC121. I enjoy the CC121, as i had before a Mackie Control Pro. Both are worth it. I now use the CC121 for Play Controls, Scrubwheel, Adjust settings with the Knob. And i switched to Cubase EQ instead of others. It is a good hardware and runs well.
