The new digital controls are awful and slow compared to the old sliders and dials.

Before that, everything was a laggy bloated unpredictable mess that sometimes registered a fingerprint

So I'm stuck with laggy, buggy, bad software and a stupid touchscreen full of features that I will never use.

The issue with theirs is terrible input lag and random hang ups similar to Phones of early vintage

Principle

Response time limits: 0.1s feels instantaneous

People report delays from a few hundred milliseconds to several seconds, so they can't tell whether an input landed, tap again, and keep their eyes on the screen longer.

More issues about response time

A fix

Show visual acknowledgment of every touch within 100 ms, rendered independently of slower back-end work, and apply knob changes such as volume locally and immediately. Make sure queued inputs don't overshoot, and measure latency on production hardware with navigation and media running.

Grouping, principle and fix drafted with Claude and reviewed by Justusability. Counts are people whose comment Claude labelled a usability complaint about this issue; see Method for how, and its limits. Something wrong here?
