I also did my ethics assignment before the deadline extension.  This week, I was able to spend some time on our actual project. I asked several questions/worries related to performance score evaluator to the professor, and was able to make some design decisions. Initially, my plan was to compare two MusicXML files by converting the user input MIDI file to MusicXML, but after trying some conversions,…

So, being able to find note heads is vital, especially since there can be more than one per component and knowing where they are as well as how many there are determines a large amount…

In general, the risks are that something just becomes trickier or take longer than we expected so our schedule will be compensated and we will need to reevaluate needs at the time and how to adjust our schedule. No changes were needed to be made to the block diagram. Certain things related to the…
