Physical model; two tube sections with scattering junction inbetween; their relative areas determine k.
| input | 
 Excitation to inject into the system  | 
| k | 
 Scattering coefficient for junction of two tubes, usually -1<=k<=1  | 
| loss | 
 Amplitude loss factor in circulation  | 
| d1length | 
 Length in samples of first delay line  | 
| d2length | 
 Length in samples of second delay line (no interpolation implemented yet)  |
