From what I can see, there's no way to add or remove elements after the onInit phase. I wonder how people handle different layouts and elements for each expansion...

I need to add some components after loading an expansion, but got this message:

Tried to add a component after onInit()

@Chazrox yes, I've added an UI toggle, so when it's on it'll route it to multiple outputs, otherwise to stereo

@dannytaurus so, UI toggle it is

This topic got a bit lengthy, so I'm posting this question here:

Since Engine.getNumPluginChannels() always returns the max outputs, even if it was added as Stereo, is there another way to detect if the plugin was inserted in the DAW either as Stereo or Multi-Output?

(I'm currently implementing an UI toggle switch, but it'd be great to detect it automatically)

EDIT: actually, maybe not. I think for a multi-output enabled plugin it will always return the max outputs, even if the plugin is loaded as a stereo version.

You're right, @dannytaurus, it always returns the max outputs. I think the UI toggle will be the only viable way.

Thanks a lot for the help!

Thanks @dannytaurus, it worked indeed! However, when I add the plugin as Stereo instead of Multi-output, the other 4 instruments, routed to outputs 3-10, are mute. Do you know how to make it work also on Stereo?

@dannytaurus I've tried a lot, with no result. The only thing that worked was changing juce_AU_Wrapper.mm. Would you have a guide on how to achieve that without changing HISE's source code?

It worked!

Thanks @dannytaurus.

It worked well on Reaper, but not in Logic.
Somehow, Logic needs to be told the output options it should offer. I've tried to use these posts you've mentioned with ChatGPT, but after trying many different things, I still couldn't figure it out.

I'm trying my plugin to have a multi-output option.

I've built HISE with these Preprocessor Definitions:

NUM_MAX_CHANNELS = 10
HISE_NUM_PLUGIN_CHANNELS = 10

I can see the multiple outputs in HISE:

But when I export the plugin, Logic only shows the Stereo options.

Does anyone know what else I need to do to enable multi-output options?

@resonant ARM64 (Windows on ARM), Windows 11, 24H2 branch (build 26100)

I've build HISE from source on Windows 11 (UTM virtual machine, Mac M1). It builds OK, but when I try to open, the cursor changes to detault/loading for a few seconds, then goes back to normal, and HISE doesn't open.

I was able to build from source on an M2 OK, but this one just doesn't open.

I've tried mulitple flags and configurations, no luck. Any clues?

Solved it. Created a junction to "remove" this 18 folder:

mklink /J "C:\Program Files\Microsoft Visual Studio\2022" "C:\Program Files\Microsoft Visual Studio\18"

I've built HISE from source, and when I clicked "Save Project and Open in IDE..." Projucer found Visual Studio no problem.

I've installed MS Build checking every single option mentioning C++.

HISE is still not recognizing MS Build installed. The path it was installed is C:\Program Files\Microsoft Visual Studio\18\Community\MSBuild, so I'm wondering if this 18 is an issue.

Any clues, anyone?

@David-Healey awesome, thanks!

@David-Healey

I've just managed to export my instrument as aaxplugin.

When I open Pro Tools (Developer Build) my plugin is not listed in the instruments list, but it's listed as instrument under the AudioSuite menu.

Any clues on how to fix this?

@David-Healey when I try to export as AAX on HISE, I get this error:

❌   "AAXStartup(IACFUnknown*)", referenced from:
❌   "AAXShutdown(IACFUnknown*)", referenced from:

❌ clang++: linker command failed with exit code 1 (use -v to see invocation)

When I then open the Xcode project and compile it, it works. So I was wondering if there is an option in HISE to generate the Projucer and Xcode files without compiling them
