The waveform/BPM admission limit is shared across imports, on-load analysis and batch jobs, so separate analysis paths cannot each start their own pair of workers. Playing audio reduces that global limit to one; reads yield between blocks. Neutral time-pitch processing is bypassed.
Loop Off cancels scheduled repeating audio immediately and resumes normal playback at the current loop position. The TV/video view presents original decoded frames directly in a display-resolution-backed layer with aspect-fit scaling, and opens at 1280×720 by default. CDG source graphics remain their original fixed resolution; scaling cannot recover missing HD detail. Settings uses a non-wrapping studio selector; the Karaoke Studio toolbar omits the Settings button.
Loop Off returns to normal file playback through the audio-clock handoff described below.

## External DJ storage
DJ Settings → Library → Move Media and Waveforms selects a destination folder, including an external drive. Imported audio is stored in its Media subfolder and saved waveforms in Waveforms. Transfers run on a utility worker with progress and cancellation; both decks and headphone preview must be stopped. Every copied file is verified before its original is removed. Waveform keys are updated for relocated audio, so saved analysis remains reusable. Folder access is remembered across launches; missing external drives are reported instead of silently creating substitute folders. The database, playlists, favourites, ratings, MIDI setup and settings stay on this Mac. Cancellation retains verified transfers and remaining originals; rerun the move to finish an interrupted transfer.
Changes to a playing loop's length are queued with the audio node at a loop boundary, avoiding a node restart. A three-millisecond seam blend reduces edge clicks without changing the loop's frame count. Loop Off still cancels repetition immediately.
Changes to a playing loop's length are queued with the audio node at a loop boundary, avoiding a node restart. A three-millisecond seam blend reduces edge clicks without changing the loop's frame count. Loop Off switches back to the source file through the same overlap.
Move progress is presented by the DJ settings pane that observes the move directly. Discovery reports progress before file matching begins, skips empty cache folders and checks each audio stamp once. Cancel responds during scanning, hashing and streaming copy; copies use 1 MB chunks and remove incomplete staging files. Large file verification/copy phases report byte counts instead of leaving the interface unchanged.

Both library toolbars share coloured, rounded action buttons and matching search fields. DJ Library groups its heading/selection/actions above filters/search/page navigation: cyan Import, green Add to Queue, purple Playlists and amber Favourites. Filter/library changes prune stale selections and clamp pagination to the current results.
Loop Off continues from a short unmodified PCM bridge into the remainder of the source file without stopping the running audio node. This avoids the stop/reschedule gap while keeping the audio clock and displayed position continuous.
Activating a loop during playback now replaces the remaining file command with a decoded continuation and the repeat buffer, without stopping the audio node. Future loops are primed until playback reaches their range. Loop Off also preserves the normal end-of-track callback when only the continuation buffer remains.
Live loop activation replaces the running file command once with the prepared loop while keeping the audio engine, effects and output route running. Repetition then runs on the audio clock; it does not seek on each UI update. Audio-output regression tests check the repeated signal, length changes and return to the file after Loop Off.
Loop activation and cancellation prepare an idle transport node while the audible node keeps running. Both feed the same effects chain. A shared host-clock start (up to 50 ms lookahead) and per-sample 12 ms complementary envelopes overlap the streams before retiring the outgoing node. The first partial loop pass uses the same processed seam as subsequent passes. Regression checks measure silent runs and adjacent-sample jumps across repeated start/stop operations, including two playing decks and changed tempos, as well as actual loop content and natural end-of-track completion.
Apple Music is available in DJ Studio’s music-source selector on macOS 14 or later. Connect uses native MusicKit authorisation; browse My Library and playlists, search the catalog, load further results, play, pause, stop, seek, skip and enqueue. Starting Apple Music while decks are playing asks before stopping deck playback and Automix. Nothing streams automatically at launch. MusicKit handles user tokens; no private keys or subscriber credentials are stored by KJMix Pro.
Enable the MusicKit App Service for the existing app identifier `com.kjamsclone.app` in the Apple Developer account, and run a signed build. The project includes `NSAppleMusicUsageDescription`; a subscription and network access are required for catalog playback. The unsigned verification build cannot validate developer-token generation or subscriber streaming. Public MusicKit uses Apple’s single application player and system audio output, not the local two-deck DSP graph: EQ/filter, crossfader, cue routing, sync, loops, waveform generation and recording of protected streamed audio are not provided. Apple-approved DJ SDK integration would require its separate documentation/access. See [Apple MusicKit](https://developer.apple.com/musickit/) and [ApplicationMusicPlayer](https://developer.apple.com/documentation/musickit/applicationmusicplayer).
