Assignment3D: Musical Instrument Digital Interface. In the early days of computing, audio files in formats like .mp3, .wav, .aiff, and .ogg didn’t really exist. To produce music (especially in gaming), computers had to synthesize it. Imagine you have a piano with 88 keys. If you press down one of those keys, then that note is "on". When you release the piano key, that note is "off". So, to encode a piano song, you just had to know when a key was turned on and how long that note should play. The on/off information was sent to a sound card that was responsible for producing the sounds (of pianos, drums and so on). That technology is called MIDI. If you want to hear an example of what it sounds like, click the Play button the right side of Wikipedia’s entry for MIDI. Interestingly, it will sound different on each different machine because sound cards vary by machine. For this assignment, you’re going to translate a MIDI value (integer) into one of 12 note values, either (C, C#, D, Eb, E, F, F#, G, Ab, A, Bb, B). That series repeats over and over again (technically to infinity). You can see an actual chart on InspiredAcoustics website or look at this MIDI Calculator. You must also determine which octave it is, which defines which repetition of the series above you’re in. For example, the value 24 is the note C - but so are 36, 48, 60 and so on. The value 24 == C1, 36 == C2, 48 == C3. You are guaranteed that the values of input will range between 24 (which is a C) to 127. Sample Output #1: MIDI value: 25 C#1 Sample Output #1: MIDI value: 94 Bb6
