hmmm I haven't been able to replicate. I'm on Mac as of writing/testing, when I get back to my windows PC I'll do another test. Maybe it's just quirky windows !

I'm on Windows 11 too but also couldn't replicate

Also couldn't replicate on Windows 11
Maybe it's a performance-related bug?

Managed to reproduce this on browser! Seems to be related to #2901

Edit: Managed to reproduce in Desktop version too.

Still haven't been able to reliably reproduce this particular issue (I can't seem to spam as fast as you're doing in the video?) but I have a theory:

The audio system has a hard cap of 32 sound channels. If a sound attempts to play while the audio system is capped, it won't play, and this can cause the instrumental to not start. If the instrumental doesn't start, that breaks the Conductor and therefore all the gameplay logic.

Reproduced on macOS. You have to spam really fast (spamming WASD and the arrow keys helps)!

That's very plausible since when I was trying to reproduce it sometimes one of the vocals would permanently stop playing instead.

In this video I managed to break both(?) vocals

If a sound attempts to play while the audio system is capped, it won't play, and this can cause the instrumental to not start.

Would it be possible to "queue" the sound to play the next time a sound channel is available if it's capped? Worst case scenario it delays the instrumental/song starting. (At least in theory?)

[Lasercar]

I wonder, is there a way a sound channel can be reserved for the instrumental and vocals? That'd be the best/easiest way to fix this, other than what poof stated above.

Also, why does this have the cannot reproduce label?
