Member Function Documentation

◆ CanExportPresets()

bool VST3Effect::CanExportPresets ( ) const

overridevirtual

Whether the effect supports export of presets to files, and importing too.

Implements EffectPlugin.

Definition at line 226 of file VST3Effect.cpp.

{
   return true;
}

◆ CopySettingsContents()

bool VST3Effect::CopySettingsContents	(	const EffectSettings &	src,
		EffectSettings &	dst
	)		const

overridevirtual

Update one settings object from another.

This may run in a worker thread, and should avoid memory allocations. Therefore do not copy the underlying std::any, but copy the contents of the contained objects.

Assume that src and dst were created and previously modified only by this

Default implementation does nothing and returns true

Parameters

src	settings to copy from
dst	settings to copy into
copyDirection	direction in which copy is performed

Returns: success
