Maestro MPTK V2.12.0 is currently in the release candidate phase! Soon available!

Now, all demos are build and available. Explore the newest release and its exceptional sound quality, honoring the FluidSynth legacy.

Info April, 24 2024

I have often this complex question: which class, attribute, or method I should use to get from relative time to absolute time and at the same time accommodate tempo and signature changes.

So I decided to create a post, look here: MIDI ticks, duration and real-time with MPTK – Maestro MPTK (paxstellar.fr)

Have your say in case of lack of clarity or error detected!

Info April, 17 2024

Finally, version 2.11.3 has been renamed to version 2.12.0. A big enhancement will be available.

Just a recall: the MPTK core synth is based on the wonderful Fluidsynth which has been translated from C to C# to propose a good integration to Unity. But MPTK was based on Fluidsynth 1.4, so a good refresh to Fluidsynth version 2.3 is in progress.

Thanks to Jonah for pointing this out. Have a look at his site https://playfulsystems.com/ it is fascinating.

Migration from Fluidsynth is not an easy task but this is now done:

• Now MPTK sounds very close to the Fluidsynth sound, thanks to the new Modulator and Generator processing.
• Will facilitate future integration of Fluidsynth enhancements.
• MPTK stays compliant to IL2CPP, so the Fluidsynth performance is preserved!

An Oboe integration update will be also available and also new APK demos . Look for details here.

Info Marsh, 09 2024

Version 2.11.3 is in progress:

• ExtendedText attribut for lyrics and all META text:
  If the value is true, Text for META (e.g. lyrics) will be write with UTF8 encoding. The default is false.
  The MIDI standard only allows ASCII characters for this META, but with this extension you will be able to read and display characters like Korean, Chinese, Japanese and even French accented letters
  To enable reading of UTF8 characters from an MPTK MIDI player, set the MidiFilePlayer#MPTK_ExtendedText attribut to true.
  
  This is an MPTK extension of the MIDI standard, so if you read your MIDI file with another application, you may not find your original text unless encoding/decoding attributs are available.

Examples:

mfw.AddText(track: 1, tick: absoluteTime, typeMeta: MPTKMeta.Lyric, text: "only ASCII");
mfw.AddText(track: 1, tick: absoluteTime, typeMeta: MPTKMeta.Lyric, text: "リリックテキスト");
mfw.AddText(track: 1, tick: absoluteTime, typeMeta: MPTKMeta.Lyric, text: "抒情文字");
mfw.AddText(track: 1, tick: absoluteTime, typeMeta: MPTKMeta.Lyric, text: "가사 텍스트");
mfw.AddText(track: 1, tick: absoluteTime, typeMeta: MPTKMeta.Lyric, text: "français éôè");
mfw.AddText(track: 1, tick: absoluteTime, typeMeta: MPTKMeta.Lyric, text: "Norsk språk");
Code language: C# (cs)

Info 14 February 2024

Version 2.11.2 is available on the Unity store with a technical improvement and a new feature:

• Technical improvement:
  • All MPTK sources are provided, which is great for understanding how MPTK works. However, a drawback is that when a change is made, even in your own script, the entire MPTK is recompiled, leading to unnecessary delays. The upcoming version split the sources into three assemblies, resulting in better separation and improved efficiency for your creations.
  • If your app doesn’t define assemblies, this change won’t affect anything (just better building perf!). However, if you do have assemblies, you’ll need to reference the MidiPlayer.Run assembly in your own assembly. In general you will have only MidiPlayer.Run to reference.

• New feature (Pro only):
  • The upcoming feature will allow you to create an MPTK runtime without including a SoundFont. With one line, an enhanced API will facilitate downloading, caching, and loading a SoundFont while your application is running. Another benefit is that you’ll be able to offer different sets of instruments to your users, which is perfect for implementing your in-app purchasing feature.
  • Look at this post for detailed information.
  • Here for the API

Info 12 December 2023

Version 2.11.1 is available on the Unity store with two fix:

• Remove weird using inserted by Unity. A “using UnityEngine.Purchasing” has been added to the script fluid_voice.cs
  It’s not the first time, does anyone have an explanation why Unity sometime adds unwanted using directive?
• Align MIDI list events in demo TestMidiFileLoad.

Info 4 December 2023

Version 2.11.0 available on the Unity store!

Change

Maestro MPTK attained the age of maturity. This new version is mainly focused on consistency and simplification. I hope you will appreciate it!

Unfortunately, API consistency affects existing projects. A helper is available to assist you with the migration. We tried to minimize your changes and provide a complete documentation.

• Migration helper here
• API v2.11.0
• Older API v2.10.0
• API change in short:
  • The MidiSynth class became too large, so we split this class into three classes:
    • MPTKChannel / MPTKChannels
    • MPTKEffectSoundFont
    • MPTKEffectUnity
    • Others MidiSynth members are not concerned.
  • Some naming error
    • MidiFileWriter2 renamed to MPTKWriter,
    • Range was not a good word for scale, so renamed to Scale
    • Remove prefix MPTK_ when not useful.
  • MidiFileLoader deprecated, replaced by MidiFilePlayer.

Fix

• Sometimes playing MIDI in MidiFileSetup stop. The AudioSource need to be restarted. Corrected.
• Corrected some design, type and translation in various parts. Thanks @Silverknight!
• MPTK_EnablePresetDrum is now available in the MidiStreamPlayer inspector. Value forced to true has been removed from this prefab.

Attempt to reduce the Garbage Collector impact

Luckily Maestro has a very good memory allocation management. When running in a built or even from the Unity Editor (without the legacy IMGUI) there is never time loss in the MIDI player or MIDI Synth.

On the other hand, all Maestro demo or editor extensions which are built with IMGUI (for example MIDI Editor) suffer of this complex issue. The only way is to translate all these demos and editor extensions to UI Toolkit. The new Unity way to build user interface. But it’s a lot of work for a low enhancement …

MIDI Editor redesigned

Info August,10 2023

• Have a look to This page is for you. you will discover Euterpe, an impressive MIDI Editor build with Unity and Maestro, of course :-).

• I’m adding a new feature to Maestro. Why not using Text Meta MIDI events for some processing on the MIDI music? It will be possible to create these meta events with a MIDI editor, from Maestro (with MidiFileWriter2 or the Midi Editor integrated to the Unity Editor, saving and loading as standard MIDI. Of course, these processing will be working only with Maestro.
  
  The more obvious will be to integrate MIDI loop information directly into the MIDI, like this for looping between tick 2000 and 3000n 3 times:

mfw.MPTK_AddText(track: 1, absoluteTime, MPTKMeta.TextEvent, "@MPTK_ACTION:INNER_LOOP_TICK(1500,2000,4000,3)");

Info July, 28 2023

• A new version will be soon available with cool new features! That will be a 2.10.0:
  • New attributes Measure and Beat associated to each MIDI events.
  • OnBeatEvent added.
  • Loop precisely inside the MIDI player with OnEventInnerLoop and the new class MPTKInnerLoop.
  • Time signature change.
  • New feature for the MIDI Editor.
• Warning: with Mac M1 and M2 architecture, in some case the DSP buffer length is not a multiple of 64: no sound will be produced or error will be displayed. Try to change the ‘DSP Buffer Size’ in the Unity Editor menu ‘Edit / Project Settings / Audio’.
  A dedicated Maestro error log message will be displayed with the next version.

Info Jun, 10 2023

• If you want to understand how to manage Maestro prefab (MidiFilePlayer, MidiStreamPlay, …) when switching between scenes, I recommend you this post.
• Interesting talk with Blinko about MIDI looping on Discord.
  • Current looping mode is designed to replay a long part of a MIDI not a few events. The MIDI sequencer is running in a system thread to get accuracy but the looping is done in Unity update() process
  • So it’s not really accurate for looping short sequence. More of that, all “silent” MIDI events (tempo change, preset change, controller change, …) are replayed from the start of the MIDI
  • A new feature, something like “MPTK_InnerLoop” will be added … soon!

Info May, 17 2023

• Warning: if you are publishing an app for Android and using IL2CPP and set managed code stripping, you will not get music in your app. That will be corrected in the next version. Nevertheless, if you have an urgent need, contact me, I will push you the change to be done (quite simple).
• Version 2.9.2 is in progress:
  • Add Preserve attribute to disable Unity linker strips (see above).
  • Add MIDI real time message to MidiKeyboard plugins.
  • TestMidiKeyboard:
    • Better design
    • Play a MIDI file with an external synth.
  • MIDI Editor:
    • Calculate and display real time related to the tempo change.
    • Add Meta section with tempo change and Text event (will be useful for sync with your app action!)

Info May, 07 2023

Version 2.9.1 available.

• MIDI Editor: Add loop points with UI [Pro]. New looping attributes: MPTK_TickStart, MPTK_TickEnd, MPTK_ModeStopVoice, MPTK_TickPlayer.
• Restore FLUID_ATTEN_POWER_FACTOR to -531.509f (some voices was not played at low velocity)
• Apply Speed change also on duration.
• Better musicality, thank to MPTK_CutOffVolume default value set to 0.0001f, was 0.05
• MidiLoop demo update

Info April, 30 2023

• Horrible regression with the last version. The change of the FLUID_ATTEN_POWER_FACTOR value was not a good idea.
• Thank Silverknight to inform me and for the help to correct. I will restore to the previous value ASAP.
• In the meantime, you can change this value in fluid_conv.cs to -531.509f. I apologize for this issue.

Info April, 26 2022

The Unity Editor Extension for creating MIDI file is ready, look here and on this site here.

PS: the MIDI Editor works only in the Unity Editor not integrated in a standalone application.

Info February, 20 2022

Version 2.9 will be soon published. The base class of the MIDI reader/writer has been rewritten.

That was mandatory for the sequencer (and a lot of works!). But the first benefit was for the MidiFileWriter2 class which has been largely rewritten. Now based only on MPTKEvent it’s easier to create a MIDI file by script.

For example, it’s now possible to join MIDI files when MIDI is playing! A new demo about this features will be also available.

BTW, the sequencer is behind the schedule. A first version will be available but with limited possibilities (no saving, no velocity edit, …). That will be an opportunity to talk with you about the future of the sequencer!

Info December, 28 2022

Info November, 29 2022

• Version 2.9.6 is available!
• Correction of the calculation of the RealTime attribute in MPTKEvent class. The time was not correct after processing a Tempo Change MIDI event. Thanks to Ken Scott for the tip, see here his app Chaotic.
• Light redesign of the SoundFont setup windows.
• Correction for Unity Editor player Midi (Midi File Player Setup window). Apply default value fir the MIDI player:

MPTK_StartPlayAtFirstNote = false; // was true
MPTK_EnableChangeTempo = true;
MPTK_ApplyRealTimeModulator = true;
MPTK_ApplyModLfo = true;
MPTK_ApplyVibLfo = true;

  • Midi Device: To reduce latency with Midi keyboard, add possibility for reading midi events from a device with a callback [Pro].
  • See “version change” for other features.
• Look here for Oboe integration in MPTK https://paxstellar.fr/oboe-fight-android-latency/

Some screen shot …

Synth parameters available for real time change:

This demo (with MPTK Pro) is useful to test latency but also the MPTK synthesizer voices run time effects and running different players at the same time. So, there is two prefabs MidiStreamPlayer for the drums and one MidiFilePlayer for the midi running at the same time.

An APK is available for those who want to test on their Android. Ask me by email, i will send you a link to the APK Euclidean Rhythm. Of course, I would be very happy to have your return.

​Infos october, 02

• We had a talk with a person wondered if a sequencer is available with MPTK. The answer is yes and no! Yes there is a Midi Sequencer able to play Midi file in background, and no, there is not an User Interface to create you own sequence. We considered that there is a lot of free sequencers able to do that better than with Unity which is limited with it’s Graphical User Interface (GUI). But the question is open! Please, give your opinion if you think that a GUI Sequencer in MPTK could be interesting. Thank by advance for your response.

Infos september,18 (a lot of news!):

• Please, have a look to this Important update on the MPTK web site : Scripting with MPTK. I hope that will help persons who want to develop scripts with MPTK.
• If you want to update MPTK to 2.841, please remove your previous version: delete folder MidiPlayer from the project tab. I apologize for that, but sync update don’t remove source file which are deleted in the new version, so conflict are detected.
• Version 2.841 s available on the store
• Horrible! The design of the two editors windows, Midi File Setup and Sound Font Setup, was ugly with Unity 2019 and 2020. Thank Unity to modify the default style of GUI!!! Corrected with this version.

Version 2.7
