Need help with importing samples via script

[A Former User]

I have a backend script that has to import some 1600 (small) samples, set various sample attributes (root, velocity, RRgroup etc) then save the sampleMap but every time I run it it crashes HISE.

What are the best practices for batch importing like this? Tried:

• Background worker with killAllVoicesAndCall which made it worse
• Switching from HDD to SSD (lol)
• inline vs regular function, inline seems to be a bit more stable but still crashy
• using less (200) samples, still crashes just as often

samples = FileSystem.findFiles(samplesFolder, "*.wav", false);

for (i=0; i<samples.length; i++)
{
	// Get sample name as string
	prefix = "{PROJECT_FOLDER}" + samplesFolder.toString(1) + "/";	
	name = samples[i].toString(3);
	path = prefix + name;

	// Set the RR Group Amount & Import Samples
	Sampler1.setAttribute(Sampler1.RRGroupAmount, NUM_ROUNDROBINS);
	var importedSamples = Sampler1.asSampler().importSamples([path], false);

for (s in importedSamples)
{	
	sT = s.get(Sampler.FileName);
	idx = sT.indexOf("root") + 4;
	subString = sT.substring(idx, sT.length);
	idxEnd = subString.indexOf("_");
	subString = subString.substring(0, idxEnd);
	rootNote = Math.round(subString);					
	
	//s.set(Sampler.LoKey, 64);		// doesn't work						

	// Low Key Fix	
	for (x = 3; x < 5; x++)
	{
		s.set(x, lowKey);
	}	
	s.set(Sampler.Root, rootNote);	
	s.set(Sampler.HiKey, highKey);
	// etc

	Sampler1.asSampler().saveCurrentSampleMap(sampleMapName);	

}

@iamlamprey No idea if this is relevant but you seem to be missing a closing bracket at the end of the first for loop.

@dannytaurus Yeh I pasted that hastily, it's part of a larger function but includes the important parts.

I just debugged it and got a seemingly unrelated error so I'm thinking the problem is actually due to this line:

Sampler1.setAttribute(Sampler1.RRGroupAmount, NUM_ROUNDROBINS);

I'll keep digging

@iamlamprey

Okay I've moved Sampler1.setAttribute(Sampler1.RRGroupAmount, NUM_ROUNDROBINS); out of the internal function so it's only being called once, silly me

okay nope, still crashing, now with a different jassert:

// if this hits, you're using multiple writer threads. consider the ScopedMultiWriteLock instead
jassert(lock.writer == thisId || lock.writer == i);

@Christoph-Hart is this a drive-related error? its an old dying HDD so I'm assuming it's related

Another error related to this line:

var importedSamples = Sampler1.asSampler().importSamples([path], false);

Exception thrown: read access violation. std::_Atomic_address_as<long,std::_Atomic_padded<int> >(...) returned 0xFFFFFFFFFFFFFFFF.

This Atomic file is part of VS2022 so I'm in uncharted waters now I think
