The iPhone app needs to pair to the Mac first so it can receive collections, cached music files, and cues over your local network. Once paired, it plays everything on the go and away from your computer.

Cueport changes your Serato library only when you choose to publish. Your edits sit in Cueport's local database as modified until you review them and push back to a specific Serato connection. Before every push, Cueport takes a restore point so that you can roll the change back, and after you first link the folder it keeps an automatic safety copy of _Serato_ in Application Support.

Yes. Open a music folder with Cueport Direct instead of linking a Serato library. Cueport analyzes tracks locally and stores cues, notes, colors, and collections in a local database on your computer.

Yes. Cueport intends to support other DJ applications one by one.

For Serato mode, open the folder that contains your _Serato_ folder, such as your Music folder or a drive root. For Cueport Direct, open the music folder you want Cueport to scan. Audio files can live under any folder name inside that selected tree, including a folder named _Serato_.

In Serato mode, Cueport reads hot cues from the GEOB frames that Serato writes into each MP3's ID3 tags. If those payloads are missing on a file, Cueport does not show a cue strip for that track. In Cueport Direct, cue points are stored in Cueport's own database.

You can edit a per-track note. In Serato mode, Cueport stores the edit locally as modified until you publish, at which point it writes the note into the Serato Comment field on the MP3. In Cueport Direct, the note remains in Cueport's own database.

No. Cueport does not collect or upload music, metadata, listening history, or analytics. No data leaves your devices except for syncing between your Mac and iPhone over your local network.

Hotel, cafe, and venue Wi-Fi often uses client isolation, which lets each device reach the internet but blocks them from talking to each other. Cueport detects this automatically and prompts you to turn on your personal hotspot. A private network or travel router also works.

The waveform strip colors are relative to the track you are playing, not an absolute frequency scale. Serato mode reads Serato's embedded overview data. Cueport Direct reads trail mix waveform columns from Cueport's database. Sections where the track's low-frequency content is higher than its own average appear orange or red. Sections near the track's midrange average appear green. Sections where high-frequency content is relatively stronger appear blue or cyan. The faint full-height lines mark bars when beatgrid markers are available. Hold on the waveform for a moment to see a quick legend.

Cueport does not handle mixing two decks, beatgrid editing, play counts, listening history, or multi-DJ shared libraries. Serato mode uses Serato's BPM, key, beatgrid, and waveform data. Cueport Direct analyzes BPM, key, and waveform locally with trail mix.
