The program doesn't really run at a constant rate and keeps stuttering so the rythms are all over the place. Too bad because otherwise it seems like a cool concept.
Win10, FF 91.0.1 64-bit
Stutters at ~24 seconds, ~32, maybe 1:30ish, 5 seconds after that... then I lost track. Not very often but when it does it's very jarring. Happens if it's running in the foreground or background, even if I'm not moving around or anything, just listening with tab in focus.
I think it should run smooth because I can play minecraft at 1440p at around 100 fps.
For me the Mad World one stutters before a single note is played: the repeater/clock seems to run, then stop, then "catches up", then stutters again, then one cycle smooth, etc. Sometimes notes are also just skipped, or only the last part of the soundbite is played.
I looked at cpu usage and it pegs a single thread to about 90% so maybe that explains it.
I have given up on any Web Audio that is not a single AudioWorklet with some kind of self contained wasm ugen
