Hi, thanks for the report. Were you by chance using the Safari browser? I checked and found that I was emitting some WebAssembly SIMD opcodes that Safari couldn't handle; I've since fixed that. The FM synth demo now works when I test it in Safari on Mac OS.

However, loading different compositions such as https://synth.ameo.dev/composition/50 seems to be causing a huge memory leak that only happens in Safari. On Chrome, the webpage uses ~330MB of RAM, but on Safari I saw it grow to over 12GB. I will have to investigate this further; I'm not sure if it's an issue with Safari, a bug in my code that only manifests on Safari, or perhaps it's the M1 memory leaks that people were talking about a month or so ago.

Anyway, thanks again for letting me know about that; I'll keep an eye out and look further into this.

I just was looking through these issues and happen to have an iPad available now. I tested in Safari and the demo works now :)
