No “Sounds” in my unit either unless I’m confusing them with Samples which I doubt based on this description in manual:
When performing a factory reset on the Digitakt, it will overwrite and re-initialize the active RAM project (in- cluding all pattern, sound pool and global data). The +Drive project slot 1 will be overwritten and re-initialized with factory preset patterns, sounds and settings. Sound bank A will be overwritten with the factory sounds.
