Function Documentation

getAudioBusConfig()

BusConfig mostly_harmless::getAudioBusConfig ( )

nodiscardnoexcept

Retrieves the current mostly_harmless::BusConfig in use for audio io.

getDescriptor()

clap_plugin_descriptor & mostly_harmless::getDescriptor ( )

nodiscard

Retrieve the currently set clap_plugin_descriptor details. This is populated via the mostly_harmless_add_plugin cmake function.

getNoteBusConfig()

BusConfig mostly_harmless::getNoteBusConfig ( )

nodiscardnoexcept

Retrieves the current mostly_harmless::BusConfig in use for midi io.

runBlockDispatch()

template<marvin::FloatType SampleType>

void mostly_harmless::runBlockDispatch	(	marvin::containers::BufferView< SampleType >	buffer,
		mostly_harmless::events::InputEventContext	eventContext,
		std::function< void(const clap_event_header *event)> &&	eventCallback,
		std::function< void(marvin::containers::BufferView< SampleType >)> &&	blockCallback )

Splits an input buffer into chunks and dispatches them, allowing for block based processing.

As parameter and note events are sample accurate, and passed via a single queue, naively doing block based processing with the entire input buffer would mean only having one param / note update event per block. To get around this, this function handles chunking the audio between events, and calling some process function with that chunk. For example:

void Plugin::process(marvin::containers::ByfferView<float> buffer, mostly_harmless::events::InputEventContext context) {
    runBlockDispatch(buffer, context,
        [this](const clap_event_header* event) -> void {
            handleEvent(event);
        },
        [this](marvin::containers::BufferView<float> chunk) -> void {
            // assuming a member called m_processor
            m_processor.process(chunk);
        }
    );
}

Parameters

buffer	The entire buffer for this block
eventCallback	The input event queue for this block.
eventCallback	A callback to invoke on a new event.
blockCallback	A callback to invoke on a new chunk.
