I'll picked xml2 because is maintained by the omnipresent Hadley Wickham, xml2 library(xml2) Both XML and xml2 packages simplifies our lives to work with xml files. GPX files are xml files with a defined defined schema GPX 1.1. At the end, I'll explain how to read it and map it in R. You can use GPSVisualizer to read the gpx file created. We save gpx_file_content to a file with the extension 'gpx' cat(gpx_file_content, file = 'output_1.gpx') I'll included the possibility to add a name to each track.

With these functions, you build the file with the two tracks. # check time is a in character with format %Y-%m-%dT%H:%M:%sZ (UTC time zone) For the sake of simplicity, I'll assume you have read both files already using your code and that you have a data frame with the two tracks information (latitude, longitude, elevation and time). I'll show three ways to merge two gpx files into one gpx file. You can use the element name to give a name to each track See the attached MIDI, in which Channel 8 has been assigned to the LH.As pointed in the first comment, the naïve solution to your problem reads Įach track has to be within. Overall, the problem is that many of the notes across channels are the same, which means that I often get the same note in the LH part and in the RH part, which makes the MIDI difficult to use. Channel 7 seemed to always contain unnecessary notes, while channel 8 had notes that could well be either in the LH or in the RH. Similarly, tracks 1, 2, 6 were combined into an RH track. Tracks 3, 4, 5 seemed to contain the lower notes, so I merged these in Anvil to form a single LH track. the notes in one channel will be relevant in some parts of the piece, and irrelevants in others. Unfortunately though, they're not all on the same channels, i.e. OK so after a couple of hours on this, I managed more or less to identify the notes - across all 8 channels - necessary to recreate what sounds like a full score of this piece.
