Chordify releases improved MIDI download feature

Just weeks since the launch of our chord edits function, we are releasing a new and improved MIDI download feature. From the early beginnings of Chordify, you have been able to download MIDI files of the chords that have been extracted from your favourite songs. But from now on, downloads will include a second MIDI file where the chords will match the exact timings of the original audio recording.

This innovation allows everyone from professional electronic dance music (EDM) producers to do it yourself (DIY) home recording artists to listen to the chords and then use them to create their own audio files or customize scores.


MIDI and Chordify
MIDI is the industry standard for controlling digital instruments, and it can also be used to create and edit sheet music. As scoring and music production require different software to attain the best results, all MIDI downloads will now comprise of two different files:

  1. A quantized version (which already existed) that is great for creating sheet music using any score writing software package (Finale, Sibelius, Musescore, etc.).
  2. A brand new time aligned version that will match the exact timings of the original audio recording. This is ideal for importing into a digital audio workstation (Cubase, Ableton, Logic, Pro Tools, etc.) in order to add additional harmonies and you can also use this version to create amazing basslines with the Chordify bassline track.

MIDI downloads are part of the Chordify Premium package. Other users can download these files for a small fee.

Scientific research for the public at large – Chordify and Utrecht University
Chordify is collaborating with its main scientific partner Utrecht University to initiate the development of this state-of-the-art crowd-sourcing platform. Scientists are investigating how chord edits can be combined in a high quality harmonic representation that can be used to evaluate and train chord recognition algorithms. We are confident that many of our enthusiastic and loyal users will edit the chord sequences from their favourite songs. With millions of monthly users, we are aiming to collect vast amounts of data to fuel this ongoing research.

The release of chord editing marks the next chapter in the fruitful partnership between Chordify and Utrecht University and will accelerate progress in automatic chord recognition research. The partners expect this implementation to ultimately lead to the most accurate chord recognition software in the world. Through crowd-sourcing, Chordify is also taking significant steps towards furthering interactivity on the platform.
