I personally hate rounded corners and shadows added everywhere. Makes most things look crappy and smudged.
Minimalism. I myself preferred the futuristic style of frutiger aero or sceumorfism (sorry for bad peeling I have dyslexia)
skeuomorphism
The only time the chunkiness of grafting visual clutter and UI elements from a machine that was designed with mechanical constraints and older use cases/capabilities makes sense is if users will not have time to learn the UI and already learned another UI.
Using knobs you have to turn with the mouse with a wooden background instead of volume slider+number field because that’s what was on some piece of audio equipment from the 1900s just makes the software awful to use. It has no place in specialist audio software the user is expected to spend hours using.
