I think C10 is a marked improvement on previous versions.
The GUI scroll experience is a lot smoother and the DAW is a lot more responsive on the whole (switching windows, re-sizing, opening/closing plugins, etc.)
The UI update is much easier on the eyes. It not only looks nicer, but the buttons are larger and clearer, and it’s done away with ‘old computer’ type presentations.
Love the ability to assign inputs/outputs when adding a new track.
Love the convenience of the Media right zone, and drag-drop ability of VST effects/instruments. (also the VST thumbnails are a great visual cue).
Vari-audio enhancements are amazing. So much flexibility at your fingertips - and so quickly.
The contextual right-click menu makes executing relevant functions or processes is more streamlined and you don’t have sift through a bunch of menu items that don’t apply.
Audio alignment tool - hello!
Stability is excellent.
… Well done Steinberg, and thank you for your well thought-out improvements. I’m sure you are dedicated to an awesome user experience, and that will only keep getting better.
