Just curious. What percentage of time do you spend on a control surface as compared to a mouse? When you have a heavy edit or mixing session, do you find you reach for the mouse or control surface for those situations?
For the most part, I just use my Control 24 to control volume/automation and panning. There are some conveniently located buttons as well for turning on quick punch, showing transport & mix window, loop play. I also use the transport controls as well (play,record,etc).
For everything else like slicing,fading,consolidating,duplicating,etc I use my mouse and keyboard shortcuts.
I am about 50/50 too on the fw-1884. Levels, muting, soloing are all on the control surface and plugins obviously with the mouse. It has eq on it as well but I always use plugin eq anyhow. Lately I've been recording my own automations with the control surface rather than drawing them with the mouse. It takes more time but it always feels and sounds better.
