Here are the classes, structs, unions and interfaces with brief descriptions:

[detail level 123]

▼NMidiPlayerTK
CMidiExternalPlayer	Play a Local MIDI file or from a Web site. This class must be used with the prefab MidiExternalPlayer
CMidiFileLoader	@Warning - will be soon deprecated, please rather use MidiFilePlayer prefab which have the same features + eventually MIDI sequencer and MIDI synth! Exemple for just loading a MIDI with MidiFilePlayer:
CMidiFilePlayer	Play a MIDI file from the MidiDB. This class must be used with the prefab MidiFilePlayer. See "Midi File Setup" in the Unity menu MPTK for adding MIDI in MidiDB.
CMidiInReader	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. More information here https://paxstellar.fr/prefab-midiinreader/
CMidiKeyboard	Base class to send and receive Midi Message from a Midi keyboard connected to the desktop
▼CMidiListPlayer	Play a list of pre-selected MIDI files from the MidiDB. This class must be used with the prefab MidiListPlayer.
CMidiListPlayerStatus	Midi Player status for the two MIDI Players defined in the MidiListPlayer.
CMPTK_MidiPlayItem	Define a MIDI file from DBMidi to be added in the list
CMidiLoad	Base class for loading a MIDI file and reading MIDI event in a MIDI sequencer. It's not possible to instanciate directly this class. Rather, use MidiFilePlayer to load a MIDI This class is used by MidiFilePlayer, MidiListPlayer, MidiFileWrite2, MidiFileLoader (see members MPTK_MidiLoaded of these classes).
CMidiPlayerGlobal	Singleton class to manage all globales MPTK features. More information here: https://paxstellar.fr/midiplayerglobal/
CMidiSpatializer	For playing Spatialized MIDI by channels or by tracks from the MidiDB. This class must be used with the prefab MidiSpatializer
CMidiStreamPlayer	Build and Play Real Time Music in relation with user actions or algorithms. This class must be used with the prefab MidiStreamPlayer.
CMidiSynth	Base class wich contains all the stuff to build a Wave Table Synth
CMPTKChannel	Description of a MIDI Channel associated to the MIDI synth. They serve to distinguish between instruments and provide independent control over each one. By transmitting MIDI messages on their respective channels, you can alter the instrument, volume, pitch, and other parameters. Within the Maestro Midi Player Toolkit, MIDI channels are designated numerically from 0 to 15. Notably, channel 9 is set aside specifically for drum sounds
CMPTKChannels	Description and list of MIDI Channels associated to the MIDI synth. Each MIDI synth has 16 channels that carry all the relevant MIDI information
CMPTKChordBuilder	Build Chord and Play with MidiStreamPlayer.
CMPTKChordLib	Build Chord from a library and Play with MidiStreamPlayer.
CMPTKEffectSoundFont	A SoundFont contains parameters to apply three kinds of effects: low-pass filter, reverb, chorus. These parameters can be specifics for each instruments and even each voices. Maestro MPTK effects are based on FluidSynth algo effects modules. Furthermore, to get more liberty from SoundFont, Maestro can increase or decrease the impact of effects (from the inspector or by script). To summarize:
CMPTKEffectUnity	Unlike SoundFont effects, they applied to the whole player. On the other hand, the Unity effects parameters are rich and, obviously based on Uniy algo! https://docs.unity3d.com/Manual/class-AudioEffectMixer.html Only most important effect are integrated in Maestro: Reverb and Chorus. On need, others effects could be added
CMPTKEvent	Description of a MIDI Event. It's the heart of MPTK! Essential to handling MIDI by script from all others classes as MidiStreamPlayer, MidiFilePlayer, MidiFileLoader, MidiFileWriter2 ...
▼CMPTKFootPrint	Experimental - Search a MIDI from a sequence of notes and calculate a score tempo.
CFootPrint	Contains detailed information about a MIDI footprint.
CMPTKInnerLoop	MIDI inner loop setting available for MidiFilePlayer and MidiExternalPlayer [Pro]. Look at MidiFilePlayer.MPTK_InnerLoop and MidiExternalPlayer.MPTK_InnerLoop. See Example:
CMPTKListItem	This class is useful when a list of paired value string+id is needed.
CMPTKScaleLib	Build Scale and Play with MidiStreamPlayer.
CMPTKSignature	Contains information about signature change.
CMPTKSoundFont	When your application is running, SoundFonts can be dynamically loaded either from a local file system or directly from the web. This means you don't need to include a SoundFont in your build, making it ideal for scenarios like in-app purchases or downloadable content. For compatibility, the legacy mode still allows loading SoundFonts from the internal MPTK database. Additionally, Maestro MPTK supports assigning different SoundFonts to different MIDI players, enabling flexible and customized audio rendering across multiple instruments or scenes.
CMPTKTempo	Contains information about the tempo change.
CMPTKWriter	Create, build, write, import, play MIDI by script. See full example with these scripts:
