\brief STK police/referee whistle instrument class.
|
|
|
|
This class implements a hybrid physical/spectral
|
|
model of a police whistle (a la Cook).
|
|
|
|
Control Change Numbers:
|
|
- Noise Gain = 4
|
|
- Fipple Modulation Frequency = 11
|
|
- Fipple Modulation Gain = 1
|
|
- Blowing Frequency Modulation = 2
|
|
- Volume = 128
|
|
|
|
by Perry R. Cook 1996 - 2010.
