Looking back at screenshots of Pro Audio 9.03, the interface looks dated—blocky, grey, and strictly utilitarian. There were no gradient curves or sleek, dark modes. However, this "ugliness" was its strength. It was lightweight. Boot times were instant. The RAM usage was measured in megabytes, not gigabytes.
