Set cue points in Serato.

No. Serato cue points are set manually. There is no native intro/drop/breakdown detection, which is why third-party tools and scripts exist to add it.

Not directly, and we would rather say that plainly: Serato's crate format cannot carry cue points, so Vibes exports crates and playlists to Serato but not cues. Vibes does auto-detect each track's structure and shows it on the waveform, so you place Serato's cues by hand with the sections already mapped. Into Rekordbox, Traktor, and Engine DJ, Vibes exports the cue points themselves.

You can. Vibes handles the structural prep automatically, and you are free to add or adjust custom performance cues in Serato on top.

Eight in Serato DJ Pro, four in Serato DJ Lite. They are saved with the track and recalled every time you load it, and they follow your files to another computer running Serato. Coming from software with more slots, the extras beyond eight will not fit, so prioritize the structural points that earn a pad.

Yes. Practice Mode runs two decks with mouse and keyboard, no hardware attached, which is enough to rehearse cue juggling and check that your points sit where the music actually turns. EQ and effects need hardware or the Serato Play expansion, but cue work practices fine without them.
