Controls :
+ 1 digital potentiometer [audio volumes for each channel/speaker]
+ 1 analog potentiometer [sequence switch]
+ 1 analog potentiometer [sequence speed]
? 1 analog potentiometer [signal shape: linear, sin, gaussian?, etc..]
? 1 analog input [trigger spatialization effect on audio input]
@todo
- add signal shape functions (lin, sin, gauss, etc..)
- add trigger input interactions
- add colliding sound walls and rotating sound slice effects
