YouTube beatmaking wizard Jelie at Kickback Couture takes a look at deCoda and how to use it to level up your sampling game by not only treating samples but also extracting chords and MIDI from the audio that can then be used inside your DAW of choice.
Adding a music theory helper app like deCoda can be a huge help for beatmakers. deCoda helps you extract the time signature, tempo, key and chord progression from any audio file. The Focus EQ will help you isolate or mute single instruments in a sample. With the pen tool, you can follow along and manually trace melodies that you can export along with the chords as MIDI for further use in your DAW of choice.
