HISE Sampler VSTs Crash? Across multiple brands (FL Win)

[Straticah]

Hey there! As you know we released Fraction a few months ago.

https://eraformaudio.com/

We are encountering a lot of customer feedback that the VST crashes inside FL studio.

The root seems to be very simple - double clicking the VST in FL(win) = crash.

We tested a couple VST Sampler from other brands, and they seem to have the same issue:

CUBE by Lunacy Audio
Fraction by Prototype Audio
MNDALA 2 by mntra-instruments

prob more HISE+webview products?

So we think its HISE related - any help is apprechiated, you may be aware of this issue @Christoph-Hart but would love to get your take/debug suggestions on this.

some customer feedback:

double clicking the VST

Can you explain this in more detail?

[Straticah]

@dannytaurus Yes sure!

Clicking this "open" button more than once (while its loading essentially)

[dannytaurus]

@Straticah I can't reproduce in FL Studio on Mac. Is this only happening on Windows?

What versions of FL Studio are affected?

Have you been able to narrow it down to a specific HISE commit, or approx date range of commits?

@Straticah I can't also reproduce it on mac with my plugins. Not sure about windows, I don't have FL Studio installed on my windows computer.

[Straticah]

Yes this issue is on FL-WIN only it seems - like always :)

[HISEnberg]

@Straticah Not happening for me on FL on Windows either (at least for my plugins). Are you using a lot of image files? It sounds like FL Studio crapping out trying to load resources from disk. This may be a DAW related issue rather than a HISE one (I know you say it happens in other DAWs however)?

Also are you using a Webview for this plugin? I imagine that may be the commonalitybetween Fraction and CUBE?

is the "make bridged" enabled ?

I havent encountered any crashes in FL Studio(Windows) so far with my plugins but i found if i double click the open button, the display window will glitch when the plugin is loaded as bridged.

[Straticah]

@HISEnberg

We are using a Webview same goes for Cube - correct. I was assuming the data refers to expansions because FX never produce this issue.

A build without bebview will be worth a test!

[bendurso]

@Straticah Oh webview on Windows could be a trigger. I had to remove the webview on windows because the plugin was loading so slowly.

I made a post a time ago about it: https://forum.hise.audio/topic/13464/webview-doesn-t-work-on-compiled-plugin-in-windows/18

[Straticah]

@bendurso It is loading slow indeed but not much slower than other VSTs.

The webview works like a charm so far (which is surprising) but it could be the issue.

Might have been coincidence theat the only HISE "other brand" vst i had installed was with a webview aswell? :D

Will know more once i bypass webview from my build...

100%

@Straticah Yea I suspect this is your culprit:

https://forum.juce.com/t/br-webview-freezes-daw/64917

Do you have enablePersistence set to true?

Do you get any useful information when running your plugin through pluginval?

[Straticah]

@HISEnberg Guys you were right the webview is the thing that crashes Lunacy audio Cube and also my plugin...

Pluginval shows no error all working fine there.

In order to NOT crash i had to remove (not only hide+deactivate) the webview panel + its code.

Seems like something thats not fixible from my side - and that a more "famous" vst has this issue gives me less hope that i will be able to solve this 🫠

[David Healey]

@Straticah I think Mndala is also using webview, does that crash for you?

[Straticah]

@David-Healey it does yes:

[David Healey]

@Straticah I'll let them know

[Straticah]

@David-Healey thank you :)

If anybody gets some insight on this - it will probably help a dozen HISE + WV plugins.

[HISEnberg]

@Christoph-Hart a good candidate for the your new Claude/Ralph system? This one is a bit over my head unfortunatley... Maybe just confirming the Webview is always running on the right thread and it is properly addressing race conditions in FL? Just a reminder the issue sounds very similar to this one: https://forum.juce.com/t/br-webview-freezes-daw/64917
