Performance MIDI-to-Score Conversion by Neural Beat Tracking

Example outputs from the test set (MAPS ENSTDkCl)

💡

Note: Both prediction and ground truth are in MIDI format. Music notations are visualised by importing the MIDI scores into MuseScore. In this page, we provide the first two lines in the Western staff notation for each example. Detailed tempo changes are not cropped.

Mozart - Sonata No. 8 D major, KV 311 (1777) - Part 1. Movement

MV2H result:

Multi-pitch	Voice	Meter	Value	Harmony	MV2H
100.0	94.1	97.6	100.0	100.0	98.3

Prediction:

Ground truth:
