The MIDI Degradation Toolkit: Symbolic Music Augmentation and Correction

Andrew Philip McLeod

In this paper, we introduce the MIDI Degradation Toolkit (MDTK), containing functions which take as input a musical excerpt (a set of notes with pitch, onset time, and duration), and return a ``degraded'' version of that excerpt with some error (or errors) ...
