The Difference between Quantized and Unquantized MIDI

The Klangio transcriptions allow you to download different formats. Let’s look at the difference between quantized and unquantized MIDI.

Downloading and opening these Formats

The different download formats of the Klangio transcriptions
Export MIDI = Quantized MIDI
Export MIDI (unq.) = Unquantized MIDI

To download these formats, start a full transcription, and export them in the top right corner of the transcription. Use either:

Simply use your Digital Audio Workstation to open and play back the MIDI files.

Quantized MIDI: Aligned to a fixed Tempo

Quantized MIDI from a Klangio transcription opened in a pianoroll viewer.
Quantized MIDI: Strictly following the tempo grid.

When opening the MIDI file into your DAW you will notice, that the notes strictly follow the tempo grid. This means, the notes will always be perfectly aligned to the set tempo (or BPM) in your DAW. However, when playing back the original audio used for the transcription, you will notice, that the MIDI is not perfectly aligned to it anymore, due to the quantization.

Furthermore, the quantized MIDI export from Piano2Notes sets a split point, allowing you to expand the MIDI over two tracks, which separates the right and left hand of the piano playing.

Unquantized MIDI: In Sync with the Original Audio

Unquantized MIDI from a Klangio transcription opened in a pianoroll viewer.
Unquantized MIDI: Ignoring the tempo grid.

The unquantized MIDI notes however are perfectly in sync with the original audio of the Transcription, but does not follow the tempo grid. Thus it is more useful if you want to capture the precise temporal nuances of the playing.
