Preset Crashes DAW

[trillbilly]

Hey Gang,

My first real day back in the studio and its been a long one already so I apologize in advance if Im missing something silly.

Im using the CustomSampleImport script and all is working great. Ive used it in other projects with no issues.

This time though, all works well within HISE Standalone, but when the plugin is exported and used in DAW (Ableton and FL Studio on Windows 10) it freezes/crashes each time a preset is selected (excluding the INIT preset which has no samples).

You can load audio files, use all fx modules, buttons, knobs, etc as normal. But once you try and load a preset, it freezes/crashes.

I checked to ensure I didnt have any knobs/buttons with "SaveInpreset" selected that were not supposed too.

Any other suggestions on why this may be happening?

@trillbilly Check inside your .preset files for issues. Maybe a non-existing component or component value outside of it's defined range?

[d.healey]

Also test it in a standalone build to rule out one of those dodgy DAWs causing the issue. :p

[trillbilly]

@Dan-Korneff no luck there. It's not a huge project so I'll attempt to rebuild and see if it persist.

@d-healey LOL these damn DAWs

[trillbilly]

@d-healey Confirmed its not the DAW.

@Dan-Korneff I rebuilt the plugin but am getting the same error. It seems to have something to do with the SampleDropper (Sample Import) within the .preset file. If I remove the value within this, the presets will load fine but without the saved audio file (obviously because I just removed it from the script).

Any suggestions on why its having issues pulling the file? I've used the CustomSampleImport script many times with no issue like this ever. Im stumped. I have no errors or compile issues.

Does the "SampleDropper" AND "SampleLoader" (Combobox) need to be set to SaveInPreset?

[DanH]

@trillbilly refer to the example project that @Christoph-Hart made and see if they are

[trillbilly]

@DanH Duh. Looks like the "SampleDropper" panel is SaveInPreset active via scripting while the SampleLoader combobox is not. This is the same way I have it in my project, so that rules that out.

I dont see any issues within the .preset files other than that. I have removed chunks at a time and it only works by removing the "SampleDropper" saved properties.

I can then go in and save the preset and use as normal. But once I close HISE I fear it will re-open with the same issue.

It even crashes HISE now as well, not just the DAW.

[Dan Korneff]

@trillbilly I would build a debug version of the plugin and make it crash. Then you can find the line of code in HISE that is failing.

[DanH]

@trillbilly have you tried with different audio files?

[trillbilly]

@Dan-Korneff my first real debugging, yes lol. I'll give this a shot and see what it comes back with.

@DanH yes, I've tried different wav files and the saved presets all do the same thing. If it has no audio file, all other knobs/button recall just fine.

@trillbilly here's a quick video I made on the general process:

[trillbilly]

@Dan-Korneff Thanks! Ill do this today hopefully

[trillbilly]

@Dan-Korneff Ok so I think I figured this out on Windows with VS. I have Ableton connected to VS and launches upon building the debug. I love my plugin in Ableton and immediately get a "Ableton Live 10 Suite.exe has triggered a breakpoint" message.

	jassert(filter != nullptr); //This line (112) is where it triggers the breakpoint.

	if (filter != nullptr)
	{
		switch (parameter)
		{
		case BandParameter::Gain:	filter->setGain(Decibels::decibelsToGain(newValue)); break;
		case BandParameter::Freq:	filter->setFrequency(newValue); break;
		case BandParameter::Q:		filter->setQ(newValue); break;
		case BandParameter::Type:	filter->setType((int)newValue); break;
		case BandParameter::Enabled:filter->setEnabled(newValue >= 0.5f); break;
		case numBandParameters:
		default:                    break;
		}
	}
	else
	{
		debugError(this, "Invalid attribute index: " + String(index));

In the Callstack, this is the only bit that has an arrow next to it

>	Mesosphere Debug.vst3!hise::CurveEq::setInternalAttribute(int index, float newValue) Line 112	C++

How do I move forward with the debugging of what looks to be a Parametric EQ? I do have 2 of them and both are Draggable Filter Panels that can be saved in preset.

[Matt_SF]

@trillbilly just taking a shot here but check your script in HISE, maybe you're addressing an eq parameter which doesn't exist...?

[trillbilly]

@Matt_SF That was my initial thought but I couldnt see anything.

The only EQs I have are for a Dry and Wet Filter. Both are also Draggable Filter Panels. Both the "FilterTile" and "WetFilterTile" have the correct ProcessorID called in the Property Settings. Both Draggable Filter Panels show and seem to work just fine.

I then use this code to add the to user preset.

//DRAGGABLE EQ SAVE IN PRESETS
//Filter
const var FilterEQ = Synth.getEffect("FilterEQ");

Engine.addModuleStateToUserPreset("FilterEQ");

//Wet Filter
const var WetFilter = Synth.getEffect("WetFilter");

Engine.addModuleStateToUserPreset("WetFilter");

The only other code I can think of that calls for anything to do with an EQ is a "Blackout" img that appears over the effect if it is powered off. This also seems to be coded correctly and working fine.

Here is how I have this scripted

//POWER BLACKOUT
//FILTER1 - DRY
const var BlackoutImage3 = Content.getComponent("BlackoutImage3");

inline function onFilterPowerbtnControl(component, value)
{
	BlackoutImage3.showControl(!value);
	Content.getComponent("FilterPowerbtn").setValue(value);
	
	FilterEQ.setAttribute(FilterEQ.setBypassed(!value), value);
	Content.getComponent("FilterPowerbtn").setValue(value);
	
};

Content.getComponent("FilterPowerbtn").setControlCallback(onFilterPowerbtnControl);

@trillbilly

this looks dodgy...to me...

FilterEQ.setAttribute(FilterEQ.setBypassed(!value), value);

[Matt_SF]

@Lindon you were quicker than me

[Lindon]

@Matt_SF said in Preset Crashes DAW:

@Lindon you were quicker than me

just passin thru....

[trillbilly]

@Lindon What would be better way for me to script something like this? I've got this on every effect module lol.

[Lindon]

@trillbilly what is the attribute you are trying to change?
