Preset Crash

[bendurso]

I'm testing my plugin with a beta tester, and it occasionally crashes for him when changing a preset. The plugin passed validation with pluginval.

I can't reproduce the crash on my Mac mini M4, but he has a 2017 Mac which is a bit slower.

The presets contain approximately 600 lines each. About 500 lines are components, 50 to 100 lines are modules, and finally, about 10 lines are macros.

The plugin shows no errors in the Hise console when changing presets. My only thought is that it crashes because his computer is slower. What do you think? Is there a way to load presets more slowly so they load properly on slower computers? Or is this already optimized with Hise?

PS: I already re-saved all the presets with the actual parameters with saveInPreset.

You built a monster :)

What do you think?

It could be, but it's not the act of loading the preset - that's pretty light on resources. It will be the action taken by some of your gazillion components when the preset loads.

How willing is the tester to try a debug version to hopefully generate a debug log when it crashes?

Of you could start commenting out control callbacks until you find the one(s) that cause the crash.

@d-healey I think I found the issue. I included "Debug mode" on the floating tile, and the beta tester sent me the log.

Most crashes happen when the convolution reverb combo box is loaded. The problem is that I'm using a convolution reverb inside a hardcoded master FX (created with Scriptnode).

In the combo box's inline function, I call Synth.getAudioSampleProcessor() only when the convolution is active. But audio processors can't be declared inside inline functions. The issue is I also can't declare them in onInit, because the convolution reverb is not loaded yet in the hardcoded master FX—so I can't call Synth.getAudioSampleProcessor()

Synth.getAudioSampleProcessor()

Yeah this is what I was saying in another thread. All references need to be declared in on init as const.

[bendurso]

@d-healey Yes, but the problem with this one is that Hise returns error if I declare on init, because there's no effect loaded on the hardcoded master fx.

@d-healey

Only after I load the Convolution Reverb network on HardcodedMasterFX1 I can get Synth.getAudioSampleProcessor. And in my plugin all hardcoded master fxs are empty on init.
