Track type identification by musical function for chord progression management

Much unknown to many, there is more than a harmonic analysis of your MIDI arrangement in Liquid Notes: a track type analysis is necessary to determine the musical function of each track in the harmonic context. This is to ensure that tracks are handled correctly when it comes to reharmonization.

Here we present you more information on how this identification works, and why it is important to deliver accurate results.


Identifying track types in MIDI arrangements

Track type identification is enabled by sophisticated machine learning algorithms that look for patterns in a track to determine what type of instrument it is, and what role it plays in your arrangement. This has been accomplished by looking for clues such as the name of an instrument, paired with algorithms that have been trained to identify before mentioned patterns in pieces of music.

The result is a highly accurate identification mechanism that maps each track into one out of four functions: melody, chords, bass or percussion. Each of these are treated differently when it comes to reharmonization, as different instruments fulfill a different role when changing chord progressions.

Hence, it is of ultimate importance that identification of tracks is accurate. Should you think that the automatic classification by Liquid Notes made an error you can simply change its value by clicking on the classification field in the open project wizard.

Normally, Liquid Notes' track type classification will work just fine in >98% of cases. But it's worth watching out, as no intelligent software is completely accurate.
