HoRNet Plugins has announced the release of SongKey MK3, an update to the key recognition tool that is also capable of detecting the chord being played and the song tempo.

The update comes with MIDI input and output for the recognized chords so you can record them and edit the track for your own needs.

At the core of SongKey we find the “chromagram” (a level representation of the intensity of each note playing in the song) but we spent a lot of time creating a more reliable and cleaner chromagram than the one of the previous version.

The data extracted from the audio is used to feed an artificial intelligence unit that is used to detect each chord, and SongKey MK3’s chord detection extends to sevenths, fifths and suspended chords.

The new key detection engine builds on the chromagram and expands it with another artificial intelligence unit based around a statistical chord progression model that analysing the chord sequence is able to understand the key of the song, this has the great advantage that the key recognition is always realtime so you can change song without the need to reset the plugin, or if the song changes key in some part of it, the plugin will simply be able to detect the new chord sequence and follow the key change.

The all new GUI is completely vector drawn and resizable, so it’ll look good on any screen and can be made smaller or bigger as needed.

HoRNet SongKey MK3 is available in VST/VST3, AU and AAX plugin formats, priced at 12.99 EUR. Owners of SongKey MK2 can upgrade for 2.99 EUR.
