Conversion issues across musical symbolic representations, such as musicXML, MEI, and humdrum, are well known. Often, these depend on methodological choices undertaken during the generation and processing of the data. For a better under-standing of this topic, we present a transcription protocol, result of trial and error transcription attempts performed with Finale engraving software, which aims to prevent conversion errors (Verovio 2.1.0 and VHV were taken into account for conversion) from musicXML (export format from Finale) to MEI and **kern (symbolic representations also evaluated).
