The #SinclairQL sound system is really pretty bonkers. Documentation is vague and even the explainers I've found are missing stuff while some others are trying to guess. At least in an emulator one can create quite odd results by giving values which don't follow the guidelines.
What was fun was that one command created sound akin to a tune by #Ø, while adding another parameter resulted in a #noise tune by #PanSonic. Awesome!
Too bad it's only 1 channel...
