So as you can see yesterday I've dumped the work of the last month to the repo and now that the CI build goes through it's expected to be compilable on macOS and Windows.

The vast amount of new features included here justify a major version bump, so I would suggest we label the next HISE meetup "HISE Release 5 party" and work our way towards that. My todo list for this includes:

• adding docs for all the new features - they will be more like references and for a high-level explanation for all the features I'll prepare a small presentation for the talk.
• creating snippets & example projects that cover the features.
• fixing bugs & regressions that I encounter when loading up different projects & stuff). It's FeatureStop (tm) at this point so we just need to round the edges of the new things.

But I could benefit from some cloud power here so if you guys could:

• making sure that everything compiles. MacOS & Windows should be covered, but my homies on Linux might want to report back if there is something going on in the land of the free over there.
• making sure there are no regressions. There were a few rather intrusive changes I had to make especially in the modulation system so if you have a project that uses a complex modulation system, please let me know if anything broke there. Especially the bridge between modulators and scriptnode is completely rewritten and there are definitively a few breaking changes that require you to tweak your nodes to adjust to the new system, but I tried to be as backwards compatible as possible and as far as I'm aware there is nothing substantive being removed.
• give me a few suggestions for snippets that cover the new feature set and I'll try to encorporate these suggestions.

Bear with me, I somehow got mixed at multiple places and now I had to commit everything to the dev branch, but todays commit history gives serial killer vibes.

There are a few gems in there that will be documented over the span of the next days:

• complete rewrite of the profiling suite (basically a extended version of Perfetto with much tighter integration into HISE). Profile your scripts down to each line of code, quickly check the DSP tree for the worst runtime & see event dependencies across different threads (broadcaster events etc).
• complex sample group manager (the UX is still all over the place and some functions are missing but the basics are there)
• WebSocket server communication for fast data transfer between web view and HISE. Oh and the Webview should now work on Linux too - David let me know if that is the case and what needs to be done to make it REALLY work.

I tried to focus on it not breaking stuff (most of the profiling tools can be completely removed with a preprocessor flag which is disabled by default), but if something behaves nasty let me know. When it's dusted off and documented, we'll call this bad boy HISE 4.5.0...

I suggest we make these things the topics of the next HISE meetup :)

Alright everybody,

it was time to finally bump the version and upload new installers. Enjoy

Hi everybody,

I'm currently profiling a project I'm working on and noticed a rather significant optimization possibility: when there is no signal input, some FX can be suspended until a signal is detected and save some CPU. This might highly improve the idle performance of your plugin, which is important for big DAW sessions.

This is not a new idea (some DAWs implement this already) and in certain parts of the HISE codebase this is already implemented, but now I refactored it to a general system and also allow DSP networks to set the flag.

This is a simple overdrive going into a 16x oversample node. With the new SuspendOnSilence flag enabled, the CPU usage goes down to literally 0% if there is no signal present. You can try to disable the flag to check the effect (it's in the DspNetwork properties, next to the AllowCompilation and HasTail properties. The flag will be passed to the node compilation, so the HardcodedFX will inherit the behaviour of the network.

Be aware that this flag should not be used if your algorithm produces any sound from silence (eg. a test tone generator or a background noise player), because it will obviously mute the output when the input is silent.

You can also see the suspend state in the Module Tree, if a FX is suspended, it will show a S over the peak meters like this:

I've tested it rather thorougly and tried to cater in all use cases (polyphonic FX will also be suspended if the voice is not producing any sound), but please let me know if you find any issues.

There's also a preprocessor macro in the hi_dsp module (HISE_SUSPENSION_TAIL_MS) which defines the time that the processing stays active after the first silence detection (the silence detection is pretty sensitive, so it looks for a -90dB threshhold), if you prefer a different default value, let me know.

In my project it yields a ~40% CPU improvement in idle mode and ~10% CPU improvement when in usage (because some channels of the plugin are not always busy). I also improved the performance of reading the peak values of routing matrixes, so this might also be a contributing factor though...

Hi everybody,

I'm very thrilled to announce that the Faust integration is merged into the develop branch and ready to test.

The implementation of the Faust integration was a Google Summer of Code project that I was mentoring together with Stéphane Letz, @sletz from the GRAME Research Lab. The project was carried out by @etXzat which I would like to introduce with a warm welcome and I'm sure he's happy to answer some questions about the process or anything Faust related as he knows much more about the actual language than I do.

The Faust language allows you to write DSP algorithms using a very concise language. It's been around for quite some time and has a lively community of developers and a vast library of existing DSP algorithms that I know all of you are dying to play around with.

The current state of the Faust integration allows the full production cycle of using Faust within a HISE project:

• add the core.faust node
• write / import Faust code using the LLVM Jit compiler. Parameters will be parsed automatically and show up as node parameters that can be connected / modulated like any other parameter
• export faust code as C++ nodes (a DSP network with a faust node will create a C++ class from the faust node and use the C++ class instead when you export the network to the DLL)
• reload them as HardcodedFX modules or nodes in scriptnode

@etXzat has written a extensive blog post about the integration process as well as the build instructions and a quick getting started guide:

By default Faust is disabled in HISE because it requires a few non-trivial configuration steps and let's be honest, HISE isn't the most easiest software to get started with so there's no need to make it even harder...

So if you want to dive into Faust development in HISE, make sure to read the build instructions on the blog post and let us know if there are any roadblocks (we've been testing it on all three platforms the last week but I wouldn't be too surprised if we missed some build issues).

Also we would like to start the discussion on what steps should be next as there are quite a few features that we couldn't realize within the projects timeframe but hopefully will be added over the next months:

• support for MIDI and polyphony (at the moment it's only possible to use Faust for audio effects)
• enhanced IDE features (editing within HISE, SVG path diagram preview, etc).
• support for complex data communication (tables / slider packs / audio files in Faust)

I've also added a new category in the HISE forum for anything faust related, so that this topic will not explode with all kinds of different questions.

After what might be the single most offensive violation of the git flow branching model in the history of software development, I finally found the motivation to merge the develop branch back into the master branch, which had a pre-pandemic state.

Also from now on, I vow to respect the traditions of software development:

• keep the master branch stable and build at all times so it can be a valid entry point for HISE newbies.
• use the develop branch for testing new features / daily development work.
• whenever I merge the develop branch into the master branch, I'll run a CI test that ensures that it builds HISE and exports a test project on macOS / windows so that @ulrik can stop being my human build bot for macOS and notify my that I broke macOS again... I will also try to bump the version numbers with each merge to master.

I'll expect the frequency of master releases to be a few weeks to months so the general advice that David healey gave in all videos since 2019 to use the develop branch for actual development stays valid.

Oh and I've thrown in VS2022 support so you don't need to crawl the web for an ancient version of 2017 anymore...

So time went on and I simplified the build process for Faust a bit so I thought I'll post the build instructions (or the link to the instructions) here and update the post once it changes:

Windows

No Projucer modifications necessary!

• Download and install Faust to the default path (C:\Program Files\Faust). The latest version is available here: https://github.com/grame-cncm/faust/releases
• Open projects/standalone/HISE Standalone.jucer and click on Save and Open in IDE
• Change the build configuration in Visual Studio to either Debug with Faust or Release with Faust. This can be done with a drop down menu in the toolbar (which initially says Debug).
• Compile this configuration. HISE will have a text label in the top bar indicating that Faust is enabled.

macOS

See here: https://github.com/christophhart/HISE/tree/develop/tools/faust

Linux

See here:
https://resonant-bytes.de/blog/gsoc-final-submission/

Then you just need to add the directory of the Faust installation to your HISE settings under FaustPath so that it can find the Faust libraries and you're good to go.

I'll lock this topic and pin it to the top now.

What's the best way to return to coding after a vacation break? Yes, adding a fun feature that is easy on the brain cells. So here I present to you:

Code snippet templates

These extend the autocomplete items with templates of commonly used code snippets. Check out how it creates a CSS definition for a button LAF within seconds:

These are the features:

• use the stock templates that come with HISE or add your own templates in a JSON file for the ultimate customization
• use the preselect range feature to create multiple selections after inserting the template

Docs:

Have fun! Also I'm happy to accept snippets to be added to the default list, so post them if you find them useful!

Alright guys, here we go:

I tried to cover a few common edge cases, but I'm sure there's lots to discover when doing monkey testing, so let me know if you find glitches...

@griffinboy Yeah I noticed that too. I think I've fixed that though with one of the latest commits - are you on the latest state?

Might be possible that I haven't pushed the fix though.

"#FFB7AA5B" is a hex representation of a colour with the #AARRGGBB format. You're almost there, you just need to turn that into an actual number with the hex format:

const var RED = 0xFFFF0000;
const var GREEN = 0xFF00FF00; // same as #FF00FF00
const var TRANSPARENT = 0; // shortcut for 0x00000000

@tomekslesicki yes there are plenty of other solutions

1. just not calling changed() in the slider would prevent the infinite loop
2. writing a custom panel instead of the buttons that store its value and is assigned to a plugin parameter would also work.
3. you could even get away with just styling the slider with a laf and make it look like a few buttons but that‘s advanced hackery and might not work with you design.

As a precautionary method: what are you trying to achieve here? Whenever people start making this distinction, it's usually a warning sign for a underlying design flaw.

Oh and another way of checking this (which also covers the case where you have assigned a MIDI controller to a knob) is to check the actual thread where this might happen from:

inline function onKnob1Control(component, value)
{
	if(Threads.getCurrentThread() == Threads.Audio)
	{
		Console.print("Plugin Parameter / MIDI controlled");
	}
	else
	{
		Console.print("UI Interaction");
	}
};

Content.getComponent("Knob1").setControlCallback(onKnob1Control);

Although that might not be 100% robust because I know that some hosts are calling the plugin parameters on a different thread (IIRC Protools does that).

@tomekslesicki You can attach a mouse broadcaster to the UI knob that will track whether you actually interact with it while changing parameters. In Pseudocode:

broadcaster.attachListener(function()
{
   IS_AUTOMATED = !event.clicked;
}

onKnob1Control(component, value)
{
    if(!IS_AUTOMATED)
    {
        // whatever...
    }
}

@Gab yes.

Big if true, but also an issue that should then be fixed by DAW devs or JUCE devs or Webview2/Webkit devs.

That's true and you can expect that DAW or JUCE devs will go out of their way to fix the stuff, but if the issue is within the Webview2 layer you're basically dead in the water as you have to engage with the developer support of Apple and Microsoft and expect them to care about our little fringe use case (compared to where webview tech is used elsewhere).

Previous versions of HISE crash if you connect this floating tile to anything other than a EQ module. Are you using the latest development branch build?

The Web tech is so far ahead of the native JUCE UI stuff in terms of what it can do

I know my arguments are a bit tainted by the sunken cost fallacy of writing C++ GUIs for 10 years and offering a framework that builds on this tech stack, but this topic is currently creating a rift in the audio developer community and the jury hasn't decided yet. I've heard multiple complaints from developers getting into trouble with multiple instances or bugs that arise when people load in different plugins that all use a webview.

I guess the only way to find out is using it in real world projects and see if it holds up to the expectations.

you also get skills that directly translate elsewhere outside HISE and even audio.

That's maybe the biggest advantage of that approach though - not only you learn web UI development alongside the process, but the pool of people you can hire grows exponentially.
