Overview
Instrument Description
Intrument 1
This instrument emulates an electric piano. For inputs it has amplitude, frequency of note, and an enveloping parameter. The enveloping is there so that the change between notes isn't abrupt. In the score section a parameter for decay and sustain is present. It allows for notes to be played as if when someone is playing a piano that their finger holds onto a note longer than others.
Intrument 2
This instrument plays the raw audio from an input file. In this case it is a song from the Katamary Damacy soundtrack. This has enveloping so that when the sample ends there isn't a harsh ending, but rather it has a fade down to zero.
Intrument 3
This is the instrument that does granular synthesis. It takes a wav file as input and then performs granular synthesis on it. For this instrument it has a different pitch for left and right ears. The resultant sound of this instrument is kind of like a record scratching many different times a second. The input wave is a song from the Katamary Damacy soundtrack.
Intrument 4
This is by far my most favourite instrument. It is a spacegun. It modulates the frequency so that when played it goes up and down ten times per second by 1/2
Song description
My favorite movie is "My Neighbor Totoro", and to pay homage to it my song starts of with first instrument 1 playing the most significant part from the main song of the movies. Then because I wanted to have fun I played the section again, however this time I used a space gun. Next to move onto the more experimental section I used Instrument 3 to create a weird noise that sounds like someone scratching a record many times per second. That sound is achieved using granular synthesis. I have also added in some overlapping of when instrument 3 plays for a nice combination of the sound. Next, instrument 2 plays, but some of instrument 3 overlaps it. To start wrapping up the song I combine several instruments over a period of time to create a unique sound. Finally we end off with a clean sound from the input file.
