@WepaAudio I would always recommend converting the samples to monolith before distribution. It's faster, takes less memory (both disk and RAM) and has almost no impacts on the sound quality unless you feed it with special test case waveforms that know how to point out the weaknesses of the HLAC codec.
Anyways, you can look at the sample map XMLs. If there are samples missing, then check if the references in there are correct.
