Stem01
Use a solo vocal take
Export the voice without backing tracks, stacked harmonies, or a long reverb tail if you can. A clear sung phrase works better than spoken words or breathy consonants, which often do not carry a stable musical pitch.
02
Expect steps where a voice slides
The current export stores pitched notes, not a continuous curve of every bend. Listen for slides, vibrato and grace notes when you compare the MIDI with the vocal. Remove small fragments if they distract from the intended phrase.
03
Turn the phrase into a new part
Try the resulting notes on a synth or keyboard sound. Adjust note lengths to suit the new instrument, and use your DAW’s pitch controls when a glide is important to the melody.
