KAR File Viewer Online

Q: Can I trust the timing?

Yes. The viewer reads tempo meta-events and the KAR division value so every lyric timestamp reflects true playback timing.

Q: Why use the snapshot feature?

Snapshots pack metadata, tempo cues, and up to 500 lyric lines into a permalink so collaborators can review the structure without sending the original KAR file.

Drop in any karaoke KAR (MIDI) file and instantly surface lyrics, tempo changes, track metadata, and pacing insights. This high-performance viewer runs locally in your browser for maximum privacy and speed.

About

This KAR file viewer lets karaoke hosts, VJ creatives, and independent arrangers audit karaoke MIDI files without installing heavy desktop software. The parser runs locally using optimized vanilla JavaScript, so you get instant insights while keeping proprietary arrangements private. Beyond basic lyric display, you receive detailed metadata, tempo tracking, and a visual pacing heatmap that reveals how busy the song feels from verse to chorus.

How to Use

Load a file by clicking the upload button or dropping a .kar file anywhere on the highlighted zone. Within seconds the interface decodes lyric, marker, track-name, tempo, and controller events alongside their exact timestamps. Use the filter box to pinpoint a chorus line, copy the cleaned lyric list to rehearsals, or export a CSV for spreadsheet audits. Tap “Create Snapshot Link” to generate a shareable permalink containing essential metadata and up to five hundred lyric events, ideal for quick collaboration.

Tips

Highlight timing conflicts by hovering the heatmap bars and watch which sections overflow with syllables. If you notice sudden tempo spikes, cross-check the markers column to confirm if deliberate count-in cues exist. For hybrid productions, run the CSV export through your DAW’s cue sheet so you can align lighting automation with lyric pacing. Because everything runs offline, consider caching this page in your browser for on-site events where Wi-Fi is unreliable.

FAQs

Can I trust the timing? Yes. The tool respects tempo meta-events and the KAR division value to keep milliseconds accurate. Does it modify my file? Never—analysis happens in-memory only. Why use the snapshot feature? It captures a lightweight summary you can paste into notes or chat without attaching the original file, speeding up review cycles for remote collaborators.
