Resource [Free Utility] Key Detector: Real-time pitch and scale detection VST3 (Windows x64)
Hi everyone,
I developed a small standalone utility called Key Detector for real-time root note and scale estimation.
**Overview:**
* **Live analysis:** Monitors incoming track signal and outputs candidate root notes and scales with certainty percentages.
* **File mode:** Drag-and-drop sample analysis directly onto the GUI.
* **Engine:** Native C++, zero added latency, low CPU usage.
**Compatibility:**
* Windows 64-bit (VST3). Tested in FL Studio.
* macOS build is currently in development.
**Download (free):**

Any feedback on detection behavior with polyphonic material or technical bug reports in FL Studio is appreciated.
