a) using additive synthesis, create the most harmonious, beautiful sound that you can. think about using multiple sin osicllators, with various levels of volume. Be very, very, very careful not to clip your sounds (ie, scale the volumes so that they add up to less then 1.0). Use many oscillators.
This has 6 oscillators, the difference between them form a C9 chord structure that can be moved depending on the x axis. Each Oscillator has its own volume that I modify in real time.

b) using additive synthesis, create the most evil, terrible, cacophonous and dissonant sound. Again, take care about volume levels.
This is the first creepy sound, as the harmonic sound, every oscillator has its own volume. In this case I am using both x and y coordinates to change the frequency and multipling them with float numbers, just random values.

c) try to see what the limit of your computer is by adding as many sin oscillators as you can together. how many can you put into the app with out it skipping. take care about the volume of each osciallator.
d) using any synthesis technique, attempt to recreate these tones:

e) working in groups of two or three, create a sequencer that allow you to compose music by controlling some parameters of synthesis over time. then, create some music with this tool.
