HoRNet SongKey MK4 is a key chords and tempo detection utility. The current version adds 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.
SongKey is very useful in those situation in which you don’t have an instrument at hand to find out the key of a song you are working on or if you are a DJ and want to make a mash up but you don’t know in which key a song is written. The chord detection feature gives you insights on the chord progression of the song so that you can better design your bass lines and pads.
