HoRNet SongKey MK3 is the all-new third version of our key finder plugin, but it doesn’t do simple key recognition, it’s also capable of detecting the chord being played and the song tempo. 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 recognized chords so you can record them and edit the track for your own needs. 

The new key detection engine builds on the chromagram and expands it with another unit based around a statistical chord progression model that analyzing 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.
