Member Function Documentation

stashMidi()

void vst3::vst_node_base::stashMidi ( )

inline

Keep this tick's events for the next block instead of dropping them. The span covers no whole sample, so every date in the tick maps to the sample the span starts on, which is offset 0 of the next block that does cover one: deferring is exact here, not an approximation.

Member Data Documentation

m_deferred

ossia::small_vector<std::pair<int, libremidi::ump>, 8> vst3::vst_node_base::m_deferred

Events from ticks that covered no whole sample, with the bus they came in on, waiting for the next block that does cover one.

m_midi_only_queues

ossia::small_vector<std::size_t, 8> vst3::vst_node_base::m_midi_only_queues

protected

Queues that exist only to carry MIDI controllers. Nothing else clears them - setControls() only touches the ones a control port backs - so dispatchMidi has to, or points accumulate block after block.
