## Detailed Description

Default implementation for a VST 3 Component.

Can be used as base class for a VST 3 component implementation.

## Constructor & Destructor Documentation

Component | ( |  | ) |

Constructor.

## Member Function Documentation

void setControllerClass | ( | const FUID & | cid | ) |
| inline

Sets the controller Class ID associated to its component.

tresult removeAudioBusses | ( |  | ) |
