Splay spreads an array of channels across the stereo field. Optional arguments are spread and center, and equal power levelCompensation. The formula for the stereo position is ((0 .. (n - 1)) * (2 / (n - 1)) - 1) * spread + center
| inArray | The array of channels to be distributed over the two stereo pairs | 
| spread | For spread = 0, all channels end up in the centre, for 1, they have maximum distribution | 
| level | An amplitude multiplier for all channels | 
| center | Shift the centre of the distribution. | 
| levelComp | 
In analogy to Mix:arFill, this method takes a function that produces the channels. The counting index is passed to it.
| n | Number of channels | 
| function | Function to return each channel | 
| spread | For spread = 0, all channels end up in the centre, for 1, they have maximum distribution | 
| level | An amplitude multiplier for all channels | 
| center | Shift the centre of the distribution. | 
| levelComp |
