Member Function Documentation

◆ initialize()

void Ase::MidiLib::MidiProducerImpl::initialize ( SpeakerArrangement busses )

overridevirtual

Mandatory method to setup parameters and I/O busses. See add_param(), add_input_bus() / add_output_bus(). This method will be called once per instance after construction.

Implements Ase::AudioProcessor.

◆ position()

Position * Ase::MidiLib::MidiProducerImpl::position ( ) const

overridevirtual

Implements Ase::MidiLib::MidiProducerIface.

Definition at line 219 of file midilib.cc.

◆ render()

void Ase::MidiLib::MidiProducerImpl::render ( uint n_frames )

overridevirtual

Method called for every audio buffer to be processed. Each connected output bus needs to be filled with n_frames, i.e. n_frames many floating point samples per channel. Using the AudioSignal::OBusId (see add_output_bus()), the floating point sample buffers can be addressed via the BusConfig structure as: bus[obusid].channel[nth].buffer, see FloatBuffer for further details. The AudioSignal::IBusId (see add_input_bus()) can be used correspondingly to retrieve input channel values.

Implements Ase::AudioProcessor.
