The most widely used postprocessing technique is the Dynamic Bayesian Network (DBN) in the form proposed by Böck et al. [9]. [...] We argue that the DBN is a problematic component because it is inherently bound to fail for several music pieces: pieces with time signature changes, pieces whose tempo falls outside of the tempo range (or that slow down/speed up outside the tempo range), and pieces whose number of beats per measure are not included in the list of supported values. [...] Remarkably, we do not use the DBN postprocessing, which was employed by all recent high-accuracy models.
