Klang is a bank of fixed frequency sine oscillators. Klang is more efficient than creating individual oscillators but offers less flexibility.
| specificationsArrayRef | 
 A Ref to an Array of three Arrays: 
  | 
| freqscale | 
 A scale factor multiplied by all frequencies at initialization time.  | 
| freqoffset | 
 An offset added to all frequencies at initialization time.  | 
The parameters in specificationsArrayRef can't be changed after it has been started. For a modulatable but less efficient version, see DynKlang.
