Xcode build fail

Hi,

I was trying to build a minimal example and followed the installation instructions of the lib on pub.dev.

I have attached an iPad via USB cable and ran flutter run . After a while I get this:

Running pod install...
Running Xcode build...
Xcode build done.                                           21,2s

[iOS] App crashes on startup for iOS simulator on M1 macbook

Whenever I add the sequencer, my app crashes on startup. I don't get clear logging, since it never finishes the "[ ] Waiting for VM Service port to be available..." step.

The error I found at some point was:
Error (Xcode): Building for 'iOS-simulator', but linking in object file
(/Users/rutgercappendijk/.pub-cache/hosted/pub.dev/flutter_sequencer-0.4.4/i
os/third_party/sfizz/build/libsfizz_fat.a[arm64]2) built for
'iOS'

Error (Xcode): Linker command failed with exit code 1 (use -v to see
invocation)

After searching around this seems to be an issue with the switch to Apple sillicon. The simulator runs on x86, while iOS and MacOS run on arm64. Some dependencies from sfizz are now built for arm64 and some for x86, and then it is impossible to link them up.

I spent a lot of hours on trying to fix this. If anyone has any input, it is very welcome!

How to switch to new audio output

Hi,
I am using Sf2Instrument to play notes from sf2 files in my piano application.

On Android, when I plugin a new USB audio device to my phone, the sound output of the library does not switch to the new device and I can not hear the notes I play after that moment.

What is the proper way of switching to the new audio device with this plugin?

FFI Support

Any plans to turn this into a FFI based plugin for cross platform support?

I also create the flutter_midi plugin which loads a SF2 file and wanting to convert it to rust or FFI.

If we could collaborate on it, I will happily deprecate my plugin and point people to this or just have a preset sound font with a higher level of abstraction around this library.

I'm also happy to chat too, my DMs are open.

Getting this log: "throwing -10878"

Getting a very vague "throwing -10878" with the custom soundfont I'm using.

Is there a way to find out what is wrong with this soundfont?

monopiano.zip

(iOS - TestFlight) Stucked at Loading...

Hi, first of all, thanks to you for this amazing lib, you did a great job!

After submitting app to test flight, I'm stuck at the text widget Loading..., it looks like files (sf2) are correctly included in the build, but somehow it won't load. Everything working great in the simulator and physical device, but only when installed directly.

Does anyone have experience with this?

I cannot debug it properly because it's only bugged in test flight and it's not crashing

EDIT:
After some time I come up to that engine is not ready... Again, only when the app is downloaded from TestFlight, in the simulator or direct install on a physical device it's working

No sound after plugging in headphones

First of all, thank you very much for the author's contribution to such an excellent library

But now there is a problem，No sound after plugging in headphones and I don't know how to fix it

Exported iOS app is unable to complete createTracks

My Situation

Flutter 2.5.2
Xcode13.0
flutter_sequencer 0.2.1 and 0.4.2 (I've tried with both but the issue not changed.)

When I build with release mode, the app able to play the sound with sf2 files properly. But on the app exported for distribution, even though it is the exact same code, it seems to stop at createTracks and not play the sound. The app doesn't crash, so I don't think it's a problem with the file path or loading.

I don't know if this is related, but when I build from Mac, I get the following messages on console when createTracks is called.

[i-aa] IPCAUClient.cpp:129:ConnectToRegistrationServer: IPCAUClient: bundle display name is nil
DLSBankManager.cpp:99:LoadInstrument: BankEntry::LoadInstrument: Unable to find patch 0 bank 0x78/0
DLSBankManager.cpp:100:LoadInstrument: about to throw -10851: LoadInstrument: Failed to load patch from bank
GlobalState.cpp:486:LoadInstrumentFromDLSCollection: DLS/SF2 bank load failed

If you have any suggestions on how to handle this, please let me know.
Thank you for developing such a cool package :)

Crash on Android 4.3

I'm getting this error reported in the Play Console. I can't say anything more so far, I'll update when I get any details from the tester who's experiencing this.

Could not build the application for the simulator.

The plugin `flutter_midi` uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

I want to fix this problem. Plz Tell me how can I fix my application. HELP ME PLZ.

CMake '3.10.2' was not found in PATH or by cmake.dir property.

I checked android studio and cmake sdk is installed. Do I need to add anything to some other file to build properly?
Also this might be related, but the IDE cannot find the Track class anywhere (I imported everything from the examples).

how to run on simulator if my mac apple silicon?

Sometimes, there is no sound when midi track plays

Thank you!this is really wonderful package, I have tested this on my android device and sometimes midi track doesn't play. I am getting logs from Audiotrack, but there is no sound.can you help me?

could not run example in ios Simulator

when i change FLUTTER_ROOT value to my path, it runs well

https://github.com/mikeperri/flutter_sequencer/blob/master/example/ios/Runner.xcodeproj/project.pbxproj

AudioKit v4 required

~~AudioKitCore cross-platform code removed from AudioKit master branch. So branch v4 of AudioKit submodule is required.~~
Git logic incorporated into build.gradle does not trigger actual pull action at least in android studio canary 2021.1.1.1 + gradle 4.1.2
Instead AudioKit v4 branch presence in .gitmodules and git recursive submodules clone performs well.

Crash when calling destroy() on Sequence

Hi!

I noticed that in Sequence's destroy() method you're iterating through a collection with forEach at the same time as you're modifying it. Not sure how this has worked before. Maybe some behavior of how iterating through the values of a map has changed recently.

void destroy() {
    _tracks.values.forEach((track) => deleteTrack(track));
    globalState.unregisterSequence(this);
}

deleteTrack now seems to be modifying the collection we are iterating through it.
A simple solution is to copy the list of track to a list before iterating through it, or just using _tracks.values.toList().forEach instead.

Adding Track throwing MissingPluginException with isAsset: true and Instruments return id=-1 if isAsset==true

I am working on adding flutter sequencer to an existing project. I have a single dart file in which I set up three instruments: a .sfz piano, a .sf2 piano, and a runtime generated synth. Other than not passing a tuning path for the .sfz file these were essentially copied from the readme example. I then use this pattern to add the tracks.

sequence.createTracks([piano, synth]).then((tracks) {
_tracks = tracks;
});

With isAsset==True, I get this error log:

E/flutter (16132): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: MissingPluginException(No implementation found for method normalizeAssetDir on channel flutter_sequencer)

E/flutter (16132):

With isAsset==False: both sfz and sf2 'addtrack' functions return a -1 id, which I believe happens in the BaseScheduler but I haven't figured out why that function fails.

The track for the synth (a RuntimeSfzInstrument) works properly, which leads me to believe that I have the package setup properly,

Please let me know if you have further questions or are able to help.

[iOS] Error EXC_BREAKPOINTEXC_BREAKPOINT

Hello,
I am experiencing an error on iOS, which occurs after playing for a while and adding new notes.
It leads to C++ code, I don't know what exactly causes the problem, but it leads to this class: SamplerBaseElement::IncrementActiveLayerVoiceCount

https://mm-mgx.sentry.io/share/issue/87f41e23f30641bdbfdef77c113a5fce/

Can someone help me please?

There is no sound in release mode but it works perfectly in debug mode [tested on iOS simulator and 2 iPhones]

Thanks a lot

Hi @mikeperri. Thank you for creating and sharing this package. The reason I want to use this package is that I need an audio library that provides very low latency playback and thankfully it does. I am also a music producer for more than 10 years. I can't stress the importance of low latency enough.

The Issue

In short, I can't make it work in release mode neither on iOS simulator nor 2 different iPhones. (Soundfonts - SF2. I tried other instrument types too).

Also I successfully uploaded the app to TestFlight and started testing on devices but no sound.

In debug mode, it runs smoothly and as expected on both iOS simulator and iPhones. I even expected and I would accept that there could be some more latency in debug mode but it is fairly good.

I am at almost end of a project and the last part is sound designing and it's like I bet all the odds on this package. So if you have time, could you please try to understand what could be the reason?

Maybe there is some basic config change could solve this. I have carefully checked all the other issues and forks/PRs of other people.

MacOS Support

Hi @mikeperri,

first of all, thanks for this awesome package! This was exactly for what I was looking for and it seems, many other developers are also excited for this package.

How much do you think is the effort, to make a port to MacOS as you wrote in the roadmap it will share most of the code of iOS?

Thanks again

Best

feat: expose preset index for sf2

SF2 files such as FluidR3_GM come with patches (preset indices) that are currently set to 0 on both Android and iOS.

Exposing a variable to set it when the instrument is created would allow developers that use sf2 to change their preset.

Could not build the precompiled application for the device in IOS.

After some discussion we determined that the important part of this error is:

malloc(296392224) failed: returning null pointer

and it's just happening when the Android emulator runs out of memory. It looks like there are two problems. One, hot reloading leaks memory, and two, the app crashes if you load too many samplers and run out of memory. It would also be great if there was a synthesizer that supports streaming samples from disk instead of loading them all into RAM. We can come back to these later.

Works in release build, not works in Archived, validated ipa build

Hi!

For some reason the sequence not loads if I try a validated archived IPA version on my phone. But it works fine in release mode. Do you guys have any idea how this can happen? I set the Build Architecture to arm64 only.

Flutter Sequencer Example crashes when headphones are used

I am considering using this Flutter library for a project, so I did some testing on it to confirm it has what I need. I got the example app building to a Google Pixel 6 Pro running Android 12 (API 31). But then I encountered issues.

When the app is opened with no audio device connected, it behaves normally and without bugs. Audio is generated and the demos are nicely functional.

When the app is opened while my MDR-XB950N1 headphones are connected via bluetooth, the app crashes with this error:

Launching lib\main.dart on Pixel 6 Pro in debug mode...

could I somehow help you, updating this plugin? Do you need more information?
I found these hints on my research:

[iOS] Using the just_audio package to play a specific mp3 is breaking the flutter_sequencer but it doensn't throw any errors.

Whenever I play an mp3 file the whole flutter_sequencer just stops. Currently using the just_audio package to play audio files.

Reproduced this issue on the example project of the flutter_sequencer by adding a simple button widget to play the mp3 file and adding the just_audio package to the pubspec.yaml file.

I crossed referenced the offending mp3 file with other working mp3 files and found out that if an mp3 has these properties the flutter_sequencer package breaks:

Audio Channel: Stereo
Sample Rate: 48 kHz

Mp3 files: Archive.zip

main.dart

        ...
            ElevatedButton(
              onPressed: () async {
                final player = AudioPlayer();
                var duration = await player.setAsset('assets/mp3/sfx-pop_mono_44k.mp3');
                player.play();
              },
              child: Text('Mono - 44k'),

                var duration = await player.setAsset('assets/mp3/sfx-pop_mono_48k.mp3');
                player.play();
              },
              child: Text('Mono - 48k'),

            ElevatedButton(
              onPressed: () async {
                final player = AudioPlayer();
                var duration = await player.setAsset('assets/mp3/sfx-pop_stereo_44k.mp3');
                player.play();
              },

                final player = AudioPlayer();
                var duration = await player.setAsset('assets/mp3/sfx-pop_stereo_48k.mp3');
                player.play();
              },
              child: Text('Stereo - 48k'),
            ),
       ...

No erros or logs are produced.

ADDITIONAL INFO:

Playing a video that has sample rate of 48k break the flutter_sequencer.
The SFZ that is currently being used for the flutter_sequencer is in 44.1k

Easy question: audiokit support on android

Easy question: i know you have replaced AudioKit Sampler with Sfizz but how were you using audiokit on android as on their project page, they say that they are only supporting apple ecosystem?

Thanks for the good work!

Cheers

Android build issues

Building for Android on Windows I had some problems, so I thought it may be helpful to add to the readme.

At first build failed because of missing NDK. I tried adding the NDK to the flutter project, but it added the latest one which was incompatible causing errors with oboe: error: use of undeclared identifier 'assert'

I eventually learned that opening the Android project would prompt me to install the correct NDK.

So my suggestion would be to include something like:

Open a file from the android folder, and choose "Open for Editing in Android Studio"
When prompted, install the NDK and let the Android project build
When it's completed, close the Android project and your flutter project should then build successfully.

On iOS it only works with silent mode off

Are there any settings to get the audio to work with the iPhone silent mode on?

Android build file on windows.

I build it on windows, i build failed with an exception: "C++ versions less than C++14 are not supported."

Development Team Error

I am getting an error when I try to run development build on iOS:

Could not build the precompiled application for the device.
Error (Xcode): Signing for "flutter_sequencer-flutter_sequencer" requires a development team. Select a development team in the Signing & Capabilities editor.
/<path>/bpm-calc-app/ios/Pods/Pods.xcodeproj

I can change the development team through XCode and run the app successfully in XCode, but I still can't run it through command/IDE (IntelliJ IDEA).

It only works in debug and profile mode

The flutter_midi plugin is not fast enough for playing single notes from an sf2 file (there's a huge of amount of delay) so I'm using your plugin with the following functions:

_selectedTrack?.startNoteNow(noteNumber: noteNumber, velocity: velocity);
_selectedTrack?.stopNoteNow(noteNumber: noteNumber);

And this plugin is super fast, thank you for your great work.

I use a midi keyboard with a pitch wheel and when I experiment with the wheel, I get pitch values between 0 (lowest) and 127 (highest).

So I assumed that, I can change the pitch of the playing note (triggered with startNoteNow() function) using the following function:

_selectedTrack?.midiPitchBendNow(value: (pitch - 64) / 64);

I assume the value parameter should be between -1 and 1.

However it has no effect on the playing note.

Can you please help about this function?

And is it also possible to apply reverb to the playing note?
