Opus Quad questions

Hello all,
I have some experience with the RX3 and now own an Opus Quad and have some questions about it.

1. smooth echo not in time
Smooth Echo I have set to 1 beat. If I now apply this to a song, the Smooth Echo works but it is not in time.  The echo is executed much slower, I know this from the DJM 909 differently, there it was perfect.
What could be the reason for this?

2. track filter only on playlists
With the RX3 I could apply the "My Tag Filter" to the entire library. With the Opus, the "edit" button only appears when I'm in a playlist.
But I want to apply the filter to the whole library (about 30 000 tracks). 
How can I set this?

3.
How can I set the 3rd column in the overview to show the rating so I can sort by it?
Thanks in advance
