Struct audio_processor_standalone_midi::vst::MidiVSTConverter

pub struct MidiVSTConverter { /* private fields */ }

This is an unsafe converter from MIDI events received from midir into the rust-vst VST api.

It’s unsafe because it must do manual memory allocation & management to interface with the VST C-style API.

Pre-allocates buffers of MIDI events up-front. Capacity is set to 100 MIDI messages by default.

More than 100 midi messages being passed into it in a single buffer tick will result in dropped messages.

The collecting phase of the audio-thread should collect at most a limit of messages.

Threshold can be changed in the future to include more.

Implementations

impl MidiVSTConverter

pub fn new(capacity: usize) -> Self

Create a new MidiVSTConverter with capacity.

Will pre-allocate buffers.

pub fn accept(&mut self, midi_message_buffer: &[MidiMessageEntry]) -> &Events

Pushes MIDI messages onto a pre-allocated Events struct. Returns a reference to it.

This should be real-time safe.

The vst::api::Events returned may be passed into a VST plugin instance.

pub fn events(&self) -> &Events

Get a reference to the events

Trait Implementations

impl Default for MidiVSTConverter

fn default() -> Self

Returns the “default value” for a type.
