MidiPlayerTK.MidiFilePlayer

This class, associated to the prefab MidiFilePlayer, is able to play music from MIDI file.
MIDI files must be added from the Unity menu MPTK in the Unity editor.
There is no need to writing a script. For a simple usage, all the job can be done in the prefab inspector.
For more information see here https://paxstellar.fr/midi-file-player-detailed-view-2/
But to more specific interaction, this class can be useful. See example below wich select randomly a MIDI to play.

On top of that, this class inherits from MidiSynth
All properties, event, methods from MidiSynth are available in the class MidiFilePlayer.

Detailed Description

This class, associated to the prefab MidiFilePlayer, is able to play music from MIDI file.
MIDI files must be added from the Unity menu MPTK in the Unity editor.
There is no need to writing a script. For a simple usage, all the job can be done in the prefab inspector.
For more information see here https://paxstellar.fr/midi-file-player-detailed-view-2/
But to more specific interaction, this class can be useful. See example below wich select randomly a MIDI to play.

On top of that, this class inherits from MidiSynth
All properties, event, methods from MidiSynth are available in the class MidiFilePlayer.

using MidiPlayerTK; // Add a reference to the MPTK namespace at the top of your script
using UnityEngine;
public class YourClass : MonoBehaviour
{
// See TestMidiFilePlayerScripting.cs for a more detailed usage of this class.
public void RandomPlay()
{
// Need a reference to the prefab MidiFilePlayer that you have added in your scene hierarchy.
MidiFilePlayer midiFilePlayer = FindObjectOfType<MidiFilePlayer>();
// Random select for the Midi
midiFilePlayer.MPTK_MidiIndex = UnityEngine.Random.Range(0, MidiPlayerGlobal.MPTK_ListMidi.Count);
// Play! How to make more simple?
midiFilePlayer.MPTK_Play();
}

◆ MPTK_StartPlayAtFirstNote

bool MidiPlayerTK.MidiFilePlayer.MPTK_StartPlayAtFirstNote

Often, the first note is not defined at the beguinning of the MIDI file (tick=0).

getset

Select a MIDI file to play by its Index.
The Index of a MIDI file is displayed in the popup from the MidiFilePlayer inspector and in the window "Midi File Setup" from the MPTK menu in the editor.

midiFilePlayer.MPTK_MidiIndex = 33;
midiFilePlayer.MPTK_Play();
Parameters
indexIndex of the MIDI, start from 0

◆ MPTK_MidiLoaded

MidiLoad MidiPlayerTK.MidiFilePlayer.MPTK_MidiLoaded
get

Get detailed information about the midi playing. This readonly properties is available only when a MIDI is playing.
Rather use the method MPTK_Load() to get information about a MIDI before playing. V2.82.

getset

Select a MIDI to play ny its name.
Use the exact name as seen in the MIDI setup windows (Unity menu MPTK/ without any path or extension.

getset

Set or get the current position in the MIDI when playing in milliseconds. Warning: if you want to set the start position, set MPTK_Position inside the processing of the event OnEventStartPlayMidi because MPTK_Play() reset the start position to 0. Other possibility to change the position in the MIDI is to use the property MPTK_TickCurrent: set or get the position in tick More info here https://paxstellar.fr/2020/09/11/midi-timing/

// Move forward one second
midiFilePlayer.MPTK_Position = midiFilePlayer.MPTK_Position + 1000d;

  • 5 = 64th Note
  • 6 = 128th Note

◆ MPTK_RealTime

Get the current tempo from the MIDI file (independent from MPTK_Speed). Return QuarterPerMinuteValue similar to BPM (Beat Per Measure)

◆ MPTK_TickCurrent

long? MidiPlayerTK.MidiFilePlayer.MPTK_TickCurrent
getset

Set or get the current tick position in the MIDI when playing. MIDI tick is an easy way to identify a position in a song independently of the time which could vary with tempo change. The count of ticks for a quarter is constant all along a Midi: see properties MPTK_DeltaTicksPerQuarterNote. Example: with a time signature of 4/4 the ticks length of a bar is 4 * MPTK_DeltaTicksPerQuarterNote. Warning: if you want to set the start position, set MPTK_TickCurrent inside the processing of the event OnEventStartPlayMidi because MPTK_Play() reset the start position to 0. Other possibility to change the position in the MIDI is to use the property MPTK_Position: set or get the position in milliseconds but tempo change event will impact also this time. More info here https://paxstellar.fr/2020/09/11/midi-timing/

◆ MPTK_TrackCount

int? MidiPlayerTK.MidiFilePlayer.MPTK_TrackCount
get

Count of track read in the MIDI file
