Classes
struct	ts::MidiEvent
	One scheduled MIDI message. More...
struct	ts::smf::SongLoop
	Loop points a file declared, in samples on the render-block grid. More...
struct	ts::smf::Song
	A parsed file: the event list plus what the container knew beyond the events. More...

Namespaces
namespace	ts
namespace	ts::smf
	A dependency-free Standard MIDI File reader.

Enumerations
enum class	ts::MidiEventKind { ts::channel , ts::sysex }
	What kind of message an event carries. More...

Functions
Song	ts::smf::load (const std::filesystem::path &path, int sample_rate=32000)
	Reads a music file, with its loop points.
Song	ts::smf::load (std::span< const std::uint8_t > data, int sample_rate=32000, std::string_view name={})
	Parses a music file held in memory, with its loop points.
std::vector< MidiEvent >	ts::smf::read (const std::filesystem::path &path, int sample_rate=32000)
	Reads a music file, ordered by position — load without the loop points.
std::vector< MidiEvent >	ts::smf::parse (std::span< const std::uint8_t > data, int sample_rate=32000)
	Parses a music file held in memory, ordered by position — load without the loop points.
std::int64_t	ts::smf::quantise (double samples) noexcept
	Rounds a sample position onto the render-block grid.

Variables
constexpr int	ts::smf::block_grid = 32
	Samples per render block — the grid events are applied on.
constexpr int	ts::smf::default_tempo = 500'000
	Default tempo when a file sets none: 120 bpm, in microseconds per quarter note.
