4.0 was definitely rushed. it's not ready.

Ive seen a few things.
1. scrolling through the all crate by dragging the scroll bar makes the tracks disappear until you let go of the scroll bar.
2. stems activation can freeze wav forms in the software and on the screens of the rane performer momentarily.
3. stem activation can actually mute the wrong part or all of the stems, ie. remove the vocal and melody, and the whole track goes mute...

*The scroll bar up and down, is impossible to see.

*I'd rather the up and down scroll was locked for just up and down, instead it allows you to move left /right at the same time.

*The 'all audio' crate is too jumpy; as are other crates. By jumpy I mean the scroll isn't fluid. Feels like the library is constantly updating as it scrolls.

*In the 'all' search, the option for which fields to search for is no longer there.

*on ddj flx 10. When in a crate or 'all audio' the scroll, knob never goes to top of the crate. It always stops two songs from the top.

*the protect metadata option is missing from 'Library & Display' options.

*can't seem to be able to drag a crate within a sub crate

flx 10 - the sampler cue button is default to 'on' and the volume of samples seems lower.

Any newly (first-time) loaded track is automatically set by Serato as a black-color track.
The platter UI fails to render correctly. Platters turn into solid black circles
platters turn into solid black circles.
If you manually set the color to black, the platter is grayish, but not blacked out.
