Exported VST causing Access Violations

[Adam_G]

@Christoph-Hart is this what im after?

[Christoph Hart]

@Adam_G nope jasserts are fine, keep on clicking on continue until you hit a access violation ;)

[Adam_G]

@Christoph-Hart took forever to get a crash for some reason haha, this?

[Christoph Hart]

@Adam_G yes that‘s the spot, now show me the callstack (bottom right panel).

[Adam_G]

@Christoph-Hart this?

[Christoph Hart]

@Adam_G nope, callstack. first tab on the right :)

[Adam_G]

@Christoph-Hart sorry found it

[Adam_G]

was that the right panel? @Christoph-Hart

[Christoph Hart]

@Adam_G Yeah, but I can't spot anything wrong in those locations. It appears to crash because you're trying to load a sample map in a scriptnode audio file slot, so maybe double check that you're not passing an invalid sample map ID in there.

Also, is it crashing when you debug the standalone version?

[Adam_G]

@Christoph-Hart that may be the cause as i have a scriptfx granulator that loads the same sample map as the sampler. i will test the standalone today but i havent been able to make it crash at all afaik

[Adam_G]

@Christoph-Hart is the way i have this written the problem perhaps?

inline function oncmbPatchesControl(component, value)
{
	slot.loadFile("{XYZ::SampleMap}" + component.getItemText());
	sampler1.loadSampleMap(sampleMaps[value-1]);
};

cmbPatches.setControlCallback(oncmbPatchesControl);

[Christoph Hart]

@Adam_G You might want to check the empty case, maybe that's what causing the problem.

[Adam_G]

@Christoph-Hart im not sure what you mean, do you mean the "slot" for the granulators sample map?

[Christoph Hart]

@Adam_G no, an if branch in the script callback thaz checks if the item text is empty and then skips the rest.

@Christoph-Hart i do have that for the preset labels default text. is this what you meant?

inline function onsliderControl(component, value)
{ 
      
    if (Engine.getCurrentUserPresetName() == "")
          Content.getComponent("lblPreset").set("text", "Default");
      else
          Content.getComponent("lblPreset").set("text", Engine.getCurrentUserPresetName());
      
};
    
Content.getComponent("slider").setControlCallback(onsliderControl);

[Adam_G]

@Christoph-Hart i should also mention the crash only happens when i use the button "reload plugin" in fl studio, or when i delete and reopen the plugin in abelton so it is happening on a reload of the plugin

[Adam_G]

@Christoph-Hart is there any other information i can provide that would help figure this out? its driving me crazy haha

[Goodflow]

@Adam_G Are you using midi floating tiles in this project?

[Adam_G]

@Goodflow yes i am, i did the fix you posted here https://forum.hise.audio/topic/4656/midi-overlay-panels-in-compiled-plugin-crashing-daws/22?_=1684334539180

it completely solved the issue in the windows version of the vst but the mac version still crashes. did you do anything differently on mac?
