Finding the key and tempo of a sample is the first hurdle in any production workflow. While many DAWs have built-in tools, they often struggle with complex chords or transient-heavy loops. The Hornet SongKey MK4 aims to solve this with a refined engine and expanded feature set. Enhanced Accuracy and Real-Time Tracking

Efficiency is everything in the studio. The MK4 introduces a scalable, vector-based GUI that looks crisp on 4K monitors.

Integrated Tuner: It features a high-precision tuner for manual correction.

Stability: Users report fewer "flickering" key detections where the plugin jumps between two related keys.

Key Changes: Unlike static detectors, MK4 can track key changes within a single track, which is vital for remixing or sampling progressive genres.

MIDI Input/Output: You can now route MIDI into SongKey to see what chords you are playing, or record the detected chords out to a MIDI track.

Advanced Chromagram: The MK4 uses a high-resolution chromagram that better distinguishes between fundamental frequencies and overtones.

Do you work mostly with or electronic samples ?

When compared to the MK3, the MK4 feels like a professional upgrade rather than a minor patch.

Instant Insight: The visual display shows the "confidence" level of the detection, so you know when the plugin is certain or if the audio is too harmonically complex.
