Synthesizer Components
This is a list of all components that were already implemented.
If you want to learn how to implement a component of your own, please refer to Creation of sound components.
Component list
Ports displayed bold are Sound ports, others are Control ports.
Hardware implementation do not exist for all components, especially for most of the control components, a hardware implementation would be rather unfeasible.
All control values are of datatype float. If the control value is used for boolean functions, then a value of 0.0 is interpreted as false, everything else as true.
