Delta Ticks Per Beat Note (or DTPQN) represent the duration time in "ticks" which make up a quarter-note.
For example, with 96 a duration of an eighth-note in the file would be 48.
From a MIDI file, this value is found in the MIDI Header and remains constant for all the MIDI file.
More info here https://paxstellar.fr/2020/09/11/midi-timing/

◆ MPTK_Duration

TimeSpan MidiPlayerTK.MidiLoad.MPTK_Duration

Real duration expressed in TimeSpan of the full midi from the first event (tick=0) to the last event.
If MPTK_KeepEndTrack is false, the MIDI events End Track are not considered to calculate this time.
The tempo changes are taken into account if MPTK_EnableChangeTempo is set to true before loading the MIDI.

◆ MPTK_DurationMS

float MidiPlayerTK.MidiLoad.MPTK_DurationMS

Real duration expressed in milliseconds of the full midi from the first event (tick=0) to the last event.
If MPTK_KeepEndTrack is false, the MIDI events End Track are not considered to calculate this time.
The tempo changes are taken into account if MPTK_EnableChangeTempo is set to true before loading the MIDI.

◆ MPTK_EnableChangeTempo

Note

Available only when a MIDI is loaded.

◆ MPTK_KeepEndTrack

bool MidiPlayerTK.MidiLoad.MPTK_KeepEndTrack

If set to true, the meta MIDI events 'End Track' are kept and the MIDI duration includes the 'End Track' events.
Default value is false.

◆ MPTK_KeepNoteOff

bool MidiPlayerTK.MidiLoad.MPTK_KeepNoteOff

A MIDI file is a kind of keyboard simulation: in general, a key pressed generates a 'note-on' and a key release generates a 'note-off'.
But there is an other possibility in a MIDI file: create a 'note-on' with a velocity=0 wich must act as a 'midi-off'
By default, MPTK create only one MPTK event with the command NoteOn and a duration.
But in some cases, you could want to keep the note-off events if they exist in the MIDI file.
Set to false if there is no need (could greatly increases the MIDI list events).
Set to true to keep 'note-off' events.

◆ MPTK_MeasureLastNote

long MidiPlayerTK.MidiLoad.MPTK_MeasureLastNote

Measure position for the last note-on found.
There is often other MIDI events after the last note-on: for example event track-end.

◆ MPTK_MicrosecondsPerQuarterNote

int MidiPlayerTK.MidiLoad.MPTK_MicrosecondsPerQuarterNote

Read from the SetTempo event: The tempo is given in micro seconds per quarter beat. To convert this to BPM we needs to use the following equation:BPM = 60,000,000/[tt tt tt] Warning: this value can change during the playing when a change tempo event is find.

Real time position in millisecond for the last note-on found in the MIDI.
There is often other MIDI events after the last note-on: for example event track-end.
Use this attribute to known the real time when all sound will be stop.
See also the MPTK_DurationMS which provides the full time of all MIDI events including track-end, control at the beginning and at the end, ....
See also MPTK_TickLastNote

◆ MPTK_Pulse

double MidiPlayerTK.MidiLoad.MPTK_Pulse

Real-time duration in millisecond of a MIDI tick. This value is updated when a tempo change is found.
The pulse length is the minimum time in millisecond between two MIDI events.

Note

Depends on the current tempo, the MPTK_DeltaTicksPerQuarterNote and the Speed.
Formula: Pulse = (60000000 / MPTK_CurrentTempo) / MPTK_DeltaTicksPerQuarterNote / 1000 / Speed

◆ MPTK_SignMap

Get the tick value of the last MIDI event played.
Set the tick value of the next MIDI event to played.
Unlike MPTK_TickPlayer which is updated continuously, this properties is updated only when a MIDI event is read from the sequencer.

Midi tick is an easy way to identify a position in a song independently of the time which could vary with tempo change event.
The count of ticks by quarter is constant all along a MIDI, it's a properties of the whole MIDI. see MPTK_DeltaTicksPerQuarterNote.
With a time signature of 4/4 the ticks length of a bar is 4 * MPTK_DeltaTicksPerQuarterNote.
More info here https://paxstellar.fr/2020/09/11/midi-timing/ @notes

Works only when the MIDI sequencer is playing.
It's not possible to set the current tick when the MIDI is not playing. Rather use the event OnEventStartPlayMidi to change the start position.
See also MidiFilePlayer::MPTK_Position: set or get the position in milliseconds.

◆ MPTK_TickEnd
