Understanding the why behind the what.
Key Shift Pro exists because audio professionals need instant, reliable key and BPM detection outside the DAW—without launching Logic, waiting for analysis, or dealing with plugin latency. It's a Mac-native utility that solves a specific, recurring problem: knowing what you're working with before you start working.
In most DAWs, key and BPM analysis happens **after** you've already imported the file, opened a project, and started working. This creates friction:
**Before you start:** You receive 20 stems from a client. You need to know which ones are in the same key, which ones match your project BPM, and which ones need pitch correction.
**Current workflow:** Import each file into Logic, wait for analysis, check the results, export notes, repeat. This takes minutes per file—and breaks your flow.
**Key Shift Pro workflow:** Drag all 20 files into Key Shift Pro. See key, BPM, and file metadata instantly. Sort, filter, and organize before you even open your DAW.
Key Shift Pro moves analysis **upstream**—before you commit to a workflow, not after.
Plugins live inside the DAW. Key Shift Pro lives **outside** the DAW. This distinction matters:
**Plugins require:** Opening a project, loading the plugin, importing audio, waiting for analysis, then exporting results.
**Key Shift Pro requires:** Dragging files into the app. That's it.
Plugins are for **processing**. Key Shift Pro is for **triage**. It answers the question 'What am I working with?' before you decide how to process it.
This is why Key Shift Pro is a **utility**, not a plugin. It solves a different problem at a different stage of the workflow.
Key Shift Pro is for professionals who work with **high volumes of audio** and need to make decisions **before** opening the DAW:
**DJs and remixers:** Sorting sample packs by key and BPM before building sets or remixes.
**Producers:** Organizing stems and loops by musical compatibility before starting a session.
**Sound designers:** Cataloging libraries and ensuring consistent metadata across assets.
**Mixing engineers:** Verifying client-provided stems match the session BPM and key before importing.
If you're working with 5-10 files per project, your DAW's built-in analysis is fine. If you're working with 50-500 files per week, Key Shift Pro saves hours.
Key Shift Pro is part of the **Kora ecosystem**, but it's also a standalone tool. You don't need Kora to use Key Shift Pro—and you don't need Key Shift Pro to use Kora.
**Standalone use:** Key Shift Pro works as a Mac-native utility for anyone who needs fast key/BPM detection.
**Integrated use:** When used with Kora, Key Shift Pro's analysis results flow into album metadata, helping you organize and deliver with full musical context.
This is the Kora philosophy: **tools that work independently, but connect when it makes sense**.
