Functions

fun filterEvents(messages: Iterable<MidiMessage>, filter: (MidiMessage) -> Boolean): Sequence<MidiMessage>

getPlayTimeMillisecondsAtTick

fun getPlayTimeMillisecondsAtTick(messages: Iterable<MidiMessage>, ticks: Int, deltaTimeSpec: Int): Int

fun getSmfBpm(data: ByteArray, offset: Int): Double

fun getSmfTempo(data: ByteArray, offset: Int): Int

getSmpteDurationInSeconds

fun getSmpteDurationInSeconds(smfDeltaTimeSpec: Int, ticks: Int, tempo: Int = DEFAULT_TEMPO, tempoRatio: Double = 1.0): Double

getSmpteTicksForSeconds

fun getSmpteTicksForSeconds(smfDeltaTimeSpec: Int, duration: Double, tempo: Int = DEFAULT_TEMPO, tempoRatio: Double = 1.0): Int

getSmpteTicksPerSeconds

fun getSmpteTicksPerSeconds(smfDeltaTimeSpec: Int): Int

Calculates ticks per seconds for SMPTE for a SMF delta time division specification raw value. frameRate should be one of 24,25,29, and 30. We dare to use UByte as the argument type to indicate that the argument is NOT the raw negative number in deltaTimeSpec.

getTotalPlayTimeMilliseconds

fun getTotalPlayTimeMilliseconds(messages: Iterable<MidiMessage>, deltaTimeSpec: Int): Int
