Methods

Add a tempo change event to a MIDI track chunk.

public static void AddTempoChange(TrackChunk track, Rational offset, int beatsPerMinute, int ticksPerQuarterNote)

track TrackChunk: The track the event is inserted into, in time order.
offset Rational: Where the change takes effect, in whole-note units.
beatsPerMinute int: The new tempo. A SetTempo event holds 24 bits, so roughly 4 is the floor.
ticksPerQuarterNote int: The time division of the file this track belongs to — read it from Melanchall.DryWetMidi.Core.MidiFile.TimeDivision, not from MidiExportOptions, whose default is 480 while a new MidiFile() uses 96. Nothing here can check it: a track does not know its file. Pass the wrong one and the event lands at the wrong time, by exactly the ratio of the two.

Add a time signature change event to a MIDI track chunk.

public static void AddTimeSignatureChange(TrackChunk track, Rational offset, int numerator, int denominator, int ticksPerQuarterNote)

track TrackChunk: The track the event is inserted into, in time order.
offset Rational: Where the change takes effect, in whole-note units.
numerator int: Beats per measure, in [1..255].
denominator int: The beat unit as it is written — 4, 8, 16 — a power of two in [1..128].
ticksPerQuarterNote int: The time division of the file this track belongs to, exactly as for AddTempoChange(TrackChunk, Rational, int, int): read it from Melanchall.DryWetMidi.Core.MidiFile.TimeDivision rather than from MidiExportOptions.
