For example, this is how the audio midi converter works in Studio One:
The Melodyne effect is open on the audio track, notes are already recognized. And simply dragging and dropping the audio clip onto the midi track converts the Audio to Midi. But these will just be approximately recognized midi notes, without any nuances such as vibrato, legato, etc. Therefore, we need an MPE.
