The UI design on the OP-1 has to be up there with any number of great moments in industrial design.

The decision to remove the Rhodes piano sample pack from the default firmware, including for anyone who upgraded, has to be up there with one of the worst decisions in product management of all time.

Also, the disparity between models with clickable control knobs and unclickable knobs to this day makes me feel deeply uncomfortable.

May we find it in our hearts to forgive. If it weren’t for their genius we wouldn’t even have noticed these minuscule flaws. Happy Birthday :)
