Manually adjust any specific note (for example the 27th note) in the MIDI editor.
So for us lay people, it sounds like the goal here is not to provide additional clarity/fidelity to the original performance, but rather to correct the "mistakes" made by the human performers in the original recording.
Is that correct?
Because if so, that sounds sort of like a more sophisticated version of auto-tune, except for instrumentation.
Does MIDI even have a clue as to what rubato is?
I’m not interested in hearing the human artistry stripped out of musical pieces by some stupid algorithms.
