Detailed Description

[MPTK PRO] Read MIDI events from a MIDI keyboard connected to your Windows or Mac desktop. This class must be used with the prefab MidiInReader

There is no need to writing a script. For a simple usage, all the job can be done in the prefab inspector.
See example of use in TestMidiInputScripting.cs
More information here https://paxstellar.fr/prefab-midiinreader/

// Example of script. See TestMidiInputScripting.cs for a more detailed usage.
// Need for a reference to the Prefab (can also be set from the hierarchy)
MidiInReader midiIn = FindObjectOfType<MidiInReader>();
 
if (midiIn == null) 
    Debug.LogWarning("Can't find a MidiInReader Prefab in the current Scene Hierarchy. Add it with the MPTK menu.");
    
// There is two methods to trigger event: in inpector from the Unity editor or by script
midiIn.OnEventInputMidi.AddListener((MPTKEvent evt) => 
{
    // your processing here
    Debug.Log(evt.ToString());
});

Member Enumeration Documentation

◆ ModeSpatializer

enum MidiPlayerTK.MidiSynth.ModeSpatializer

inherited

[MPTK PRO] Spatializer Mode for the prefab MidiSpatializer

Enumerator
Channel	Spatial Synth are enabled to dispatch note-on by channels. As a reminder, only one instrument at at time can be played by a MIDI channel Instrument (preset) are defined by channel with the MIDI message MPTKCommand.PatchChange
Track	Spatial Synth are enabled to dispatch note-on by tracks defined in the MIDI. As a reminder, multiple channels can be played on a tracks, so multiple instruments can be played on a Synth. Track name are defined with the Meta MIDI message SequenceTrackName. This MIDI message is always defined in MIDI, so name can be missing.

Member Function Documentation

Parameters

channel must be between 0 and 15

Returns: channel count

◆ MPTK_ChannelEnableGet()

bool MidiPlayerTK.MidiSynth.MPTK_ChannelEnableGet ( int channel )

inherited

Is channel is enabled or disabled.

		bool	enable
	)

inherited

Disable (mute) or enable (unmute) a MIDI channel.

Parameters

channel	must be between 0 and 15
enable	true to unmute (default), false to mute channel

◆ MPTK_ChannelForcedPresetGet()

int MidiPlayerTK.MidiSynth.MPTK_ChannelForcedPresetGet ( int channel )

inherited

Set forced preset on the channel. MIDI will allways playing with this preset even if a MIDI Preset Change message is received.
Set to -1 to disable this behavior.

Parameters

channel

Returns: preset index, -1 if not set

int preset = midiFilePlayer.MPTK_ChannelForcedPresetGet(channel);
int bank = midiFilePlayer.MPTK_ChannelBankGetIndex(channel);
GUILayout.Label($"{preset} / {bank}");
int forcedPreset = (int)GUILayout.HorizontalSlider(preset, -1f, 127f);
if (forcedPreset != preset)
   midiFilePlayer.MPTK_ChannelForcedPresetSet(channel, forcedPreset);

◆ MPTK_ChannelForcedPresetSet()

bool MidiPlayerTK.MidiSynth.MPTK_ChannelForcedPresetSet	(	int	channel,
		int	preset,
		int	bank = `-1`
	)

inherited

Set a Preset on a channel to force the MIDI Synth to always playing with this instrument even if MIDI 'Preset Change' or 'Bank change' messages are received.
Set Preset to -1 to restore the Preset and Bank defined in the MIDI file.

Parameters

channel	0 to 15 channel
preset	Preset to force in the range 0 to 127 preset. Set to -1 to restore the Preset and Bank known from the MIDI file.
bank	Optionnal. Bank to force in the range 0 to 128. Set to -1 to restore to the last bank known from the MIDI file.

Returns: true if the preset/bank exists in the current SoudFont, otherwise false

// Example of changing the forced preset with the Unity GUI.
// ---------------------------------------------------------
int preset = midiFilePlayer.MPTK_ChannelPresetGetIndex(channel);
 
// Slider to change the preset on this channel from -1 (disable forced) to 127
// The forced bank is defined from the inspector.
int forcePreset = (int)GUILayout.HorizontalSlider(preset, -1f, 127f);
 
if (forcePreset != preset)
{
    // Force a preset whatever the MIDI events from the MIDI file.
    midiFilePlayer.MPTK_ChannelForcedPresetSet(channel, forcePreset);
}

Another example with MidiExternalPlayer.

// To force the preset from the start of the playing,
// the forced preset and the forced bank must be set 
// after the MIDI is loaded and before any MIDI message is played.
// The OnEventStartPlayMidi event is perfect for that.
// ---------------------------------------------------------------
 
// Get the prefab added to the hierarchy of the current scene
MidiExternalPlayer midiPlayer = FindObjectOfType<MidiExternalPlayer>();
 
// Set the listener on the event OnEventStartPlayMidi
midiPlayer.OnEventStartPlayMidi.AddListener((string midiName) =>
    {
        // Each time the MIDI is started this script is run
        // Force preset 70 for note-on on channel 0 (Bassoon is GM SoundFont)
        midiPlayer.MPTK_ChannelForcedPresetSet(0, 70, 1);
    });

◆ MPTK_ChannelInfo()

string MidiPlayerTK.MidiSynth.MPTK_ChannelInfo ( int channel )

inherited

Build an information string about the channel. It's also a good pretext to display an example of Channel API.

◆ MPTK_ChannelNoteCount()

int MidiPlayerTK.MidiSynth.MPTK_ChannelNoteCount ( int channel )

inherited

Get count of notes played since the start of the MIDI.

Parameters

channel must be between 0 and 15

◆ MPTK_ChannelPresetChange()

bool MidiPlayerTK.MidiSynth.MPTK_ChannelPresetChange	(	int	channel,
		int	preset,
		int	bank = `-1`
	)

inherited

Change the Preset and/or Bank associated to a Channel.
The new value of the bank or preset are registered in the channel even if the preset or bannk is not found.
Each channel can have a different bank/preset set.
Note 1: When bank is changed, the preset list is not updated (MidiPlayerGlobal.MPTK_ListPreset). Call MidiPlayerGlobal.MPTK_SelectBankInstrument to refresh this list.
Note 2: When playing a MIDI file, MIDI messages like "Patch Change" and "ControlChange BankSelectMsb" will override value registered with this method.
Note 3: To change globally the bank, use instead the global methods: MidiPlayerGlobal.MPTK_SelectBankInstrument or MidiPlayerGlobal.MPTK_SelectBankDrum.
Note 4: The method MPTK_ChannelForcedPresetSet can be used to force the preset whatever the MIDI messages.

 
                // Change bank or preset with free value with MPTK_ChannelPresetChange
                // -------------------------------------------------------------------
 
                // Select any value in the range 0 and 128 for the bank 
                int bank = (int)Slider("Free Bank", midiStreamPlayer.MPTK_ChannelBankGetIndex(StreamChannel), 0, 128, false, 100, 200);
                // Select any value in the range 0 and 127 for the preset
                int prst = (int)Slider("Free Preset", midiStreamPlayer.MPTK_ChannelPresetGetIndex(StreamChannel), 0, 127, true, 100, 200);
                // If user made change for bank or preset ...
                if (bank != midiStreamPlayer.MPTK_ChannelBankGetIndex(StreamChannel) ||
                    prst != midiStreamPlayer.MPTK_ChannelPresetGetIndex(StreamChannel))
                {
                    // ... apply the change to the MidiStreamPlayer for the current channel.
                    // If the bank or the preset doestn't exist 
                    //      - the method returns false 
                    //      - the bank and preset are still registered in the channel
                    //      - when a note-on is received on this channel, the first preset of the first bank is used to play (usually piano).
                    bool ret = midiStreamPlayer.MPTK_ChannelPresetChange(StreamChannel, prst, bank);
 
                    // Read the current bank, preset and preset name selected
                    int newbank = midiStreamPlayer.MPTK_ChannelBankGetIndex(StreamChannel);
                    int newpreset = midiStreamPlayer.MPTK_ChannelPresetGetIndex(StreamChannel);
                    string newname = midiStreamPlayer.MPTK_ChannelPresetGetName(StreamChannel);
                    Debug.Log($"MPTK_ChannelPresetChange result:{ret} bank:{newbank} preset:{newpreset} '{newname}'");
                }

Parameters

channel	0 to 15. There is 16 channels available in the MIDI norm.
preset	The total number of presets available depend on the soundfont selected
bank	Optionnal, if not set or -1 the current bank will be applied (or default bank if never set). Default bank is defined globally: menu MPTK / SoundFont Setup.

◆ OnMidiEvent

Action<MPTKEvent> MidiPlayerTK.MidiSynth.OnMidiEvent

inherited

[MPTK PRO] V2.89.0 - This function is called by the MIDI sequencer before sending the MIDI message to the MIDI synthesizer.
It can be used like a MIDI events preprocessor: it's possible to change the value of the MIDI events and therefore change the playback of the song.
The callback function receives a MPTKEvent object by reference (normal, it's a C# class).
Look at https://mptkapi.paxstellar.com/d9/d50/class_midi_player_t_k_1_1_m_p_t_k_event.html
A lot change is possible on the MIDI event: change note, velocity, channel, ..., even changing the MIDI type of the message!!!
See below some examples of changes.

Note 1: the callback is running on a system thread not on the Unity thread. Unity API call is not possible except for the Debug.Log (to be gently used, it consumes CPU)
Note 2: avoid heavy processing or waiting inside the callback otherwise MIDI playing accuracy will be bad.
Note 3: the midiEvent is passed by reference to the callback, so re-instanciate object (midiEvent = new MPTKEvent()) or set to null, has no effect!
Note 4: MIDI position attributs (Tick and RealTime) can be used in your algo but changing their values has no effect, it's too late!
Note 5: Changing SetTempo event is too late for the MIDI Sequencer (already taken into account). But you can use midiFilePlayer.MPTK_Tempo to change the tempo

// See TestMidiFilePlayerScripting.cs for the demo.

getinherited

[MPTK PRO] If spatialization is track mode, contains the last name of the track

◆ MPTK_TransExcludedChannel

int MidiPlayerTK.MidiSynth.MPTK_TransExcludedChannel

getsetinherited

Transpose will apply to all channels except this one. Set to -1 to apply to all channel. V2.89.0
Default is 9 because generally we don't want to transpose drum channel.

◆ MPTK_Transpose

int MidiPlayerTK.MidiSynth.MPTK_Transpose

getsetinherited

Transpose note from -24 to 24

◆ MPTK_Volume

float MidiPlayerTK.MidiSynth.MPTK_Volume

getsetinherited

Global Volume. apply to all channels.
Must be >=0 and <= 1

Event Documentation

◆ OnAudioFrameStart

OnAudioFrameStartHandler MidiPlayerTK.MidiSynth.OnAudioFrameStart

inherited

[MPTK PRO] this event is triggered at each start of a new audio frame from the audio engine.
The parameter (double) is the current synth time in milliseconds. See example of use.
The callbach function will not run on the Unity thread, so you can't call Unity API except Debug.Log.

// See Assets\MidiPlayer\Demo\ProDemos\Script\EuclideSeq\TestEuclideanRhythme.cs for the full code.
public void Play()
{
    if (IsPlaying)
        midiStream.OnAudioFrameStart += PlayHits;
    else
        midiStream.OnAudioFrameStart -= PlayHits;
}
private void PlayHits(double synthTimeMS)
{
    if (lastSynthTime <= 0d)
        // First call, init the last time
        lastSynthTime = synthTimeMS;
    // Calculate time in millisecond since the last loop
    double deltaTime = synthTimeMS - lastSynthTime;
    lastSynthTime = synthTimeMS;
    timeMidiFromStartPlay += deltaTime;
 
    // Calculate time since last beat played
    timeSinceLastBeat += deltaTime;
 
    // Slider SldTempo in BPM.
    //  60 BPM means 60 beats in each minute, 1 beat per second, 1000 ms between beat.
    // 120 BPM would be twice as fast: 120 beats in each minute, 2 per second, 500 ms between beat.
    // Calculate the delay between two quarter notes in millisecond
    CurrentTempo = (60d / SldTempo.Value) * 1000d;
 
    // Is it time to play a hit ?
    if (IsPlaying && timeSinceLastBeat > CurrentTempo)
    {
        timeSinceLastBeat = 0d;
        CurrentBeat++;
    }
