Detailed Description

template<typename T>
class pongasoft::VST::RT::RTVstParameter< T >

The typed version.

Maintains the denormalized (aka "typed") version of the value and previous value.

◆ resetPreviousValue()

bool resetPreviousValue ( )
overrideprotectedvirtual

Called at the end of the frame so that previous value is set to current value for the next frame.

Returns
true if previous value was different than current value

Reimplemented from RTRawVstParameter.

◆ update()

void update ( ParamType const &  iNewValue)

This method is typically called during the processing method when the plugin needs to update the value.

In general the change needs to be propagated to the VST sdk (using addToOutput).

◆ updateNormalizedValue()

bool updateNormalizedValue ( ParamValue  iNormalizedValue)
overrideprotectedvirtual

Update the parameter with a new normalized value.

This is typically called after the VST parameter managed by the VST sdk changes (for example, moving a knob or loading a previously saved plugin)

Returns
true if the value was actually updated, false if it is the same

Reimplemented from RTRawVstParameter.
