Frequency Modulation Some other Methods
==================== ==================
* Modulate frequency inlet with an other oscilator
* 1973 John Chowning
* Multiple oscilators can be arbitraily combined to fm each other
* Lots of possibilities
* Difficult to find a specific sound

Amplitude Modulation
====================
* Works similar to FM, but uses amplitude slot
* doesn't have the rich possibilities of FM

Physical Modeling
=================
* Best known is Karplus-Strong * Frequency Modulation
* Uses Delaylines * Amplitude Modulation
* Simulates Strings and Flutes, both of which base on sine waves reflected back at the boundary * Physical Modelling
* Various Oscilators are used Van-der-Poole, Chua or strange attractors like Henon, Lorentz
