The two chromagrams (the one used for chord recognition and the one for key recognition) are shown on the GUI so that you can know which notes are playing and which ones you can use for your track, also we added a handy keyboard display that allows you to see which keys are being played. 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, all of this working just on your DAW, with no need for an internet connection. The data extracted from the audio is used to feed a simple artificial intelligence unit that is used to detect each chord, and SongKey MK4’s chord detection extends to sevenths, fifths and suspended chords. We have put great attention improving the “chromagram” a level representation of the intensity of each note playing in the song taking into consideration a wider range of octaves and filtering out some slight out of tune sounds. Of course this new SongKey provides better accuracy in every aspect: key recognition is faster and more precise, chords are detected more precisely and tempo is more accurate. We thought it was a good idea to also add MIDI input (to be able to detect chords and key of midi tracks) and MIDI output for the recognised chords so you can record them and edit the track for your own needs, also SongKey MK4 provides new standalone version that is able to generate midi clock to keep all your other M IDI gear in sync with a live audio input. HoRNet SongKey MK4 is the fourth version of our key recognition tool, but it doesn’t do simple key recognition, it’s also capable of detecting the chord being played and the song tempo.
