func (Marker) Text

func (m Marker) Text() string

type Message

type Message interface {
	String() string
	Raw() []byte
	// contains filtered or unexported methods
}

type ProgramName

type ProgramName string

func (ProgramName) Raw

func (m ProgramName) Raw() []byte

func (ProgramName) String

func (m ProgramName) String() string

ProgramName

FF 08 length text

This optional event is used to embed the patch/program name that is called up by the immediately subsequent Bank Select and Program Change messages. It serves to aid the end user in making an intelligent program choice when using different hardware.

This event may appear anywhere in a track, and there may be multiple occurrences within a track.

func (ProgramName) Text

func (m ProgramName) Text() string

type Reader

type Reader interface {
	// Read reads a single Meta Message.
	// It may just be called once per Reader. A second call returns io.EOF
	Read() (Message, error)
}

Reader reads a Meta Message

func NewReader

func NewReader(input io.Reader, typ byte) Reader

NewReader returns a reader that can read a single Meta Message Read may just be called once per Reader. A second call returns io.EOF

type SMPTEOffset

type SMPTEOffset struct {
	Hour            byte
	Minute          byte
	Second          byte
	Frame           byte
	FractionalFrame byte
}

func (SMPTEOffset) Raw

func (s SMPTEOffset) Raw() []byte

func (SMPTEOffset) String

func (s SMPTEOffset) String() string
