How to convert polyphonic audio recordings into editable MIDI data using modern melody and chord transcription algorithms.
#1 Why Transcribe Audio to MIDI?
Audio stems are fixed audio files. Converting an audio stem into MIDI unlocks complete freedom: change the instrument from a piano to an 80s synth, edit individual wrong notes, or transpose voicings.
#2 Using Melodyne or Ableton Audio-to-MIDI
Isolate the single instrument stem in Musivo at /studio/stems. In Ableton Live, right-click the stem and choose 'Convert Harmony to New MIDI Track'. Ableton extracts the chord voicings into clean MIDI notes.
#3 Assigning Custom VST Instruments
Route the extracted MIDI data into high-end virtual instruments like Omnisphere, Kontakt, or Serum for custom sound design.
Studio Production Key Takeaway
"Isolating single-instrument stems before running audio-to-MIDI algorithms dramatically increases chord transcription accuracy."
