How to make both characters play their animation once during hold notes without loop/stutter

[AnchovyRodent]

Describe your problem here.

I haven't seen anyone post or talk about this at all ever, but it's a thing that's kinda been bothering me for a long time now.

I want to figure out how to make both the playable and opponent character in a song to play their singing animation once during hold notes and staying on their last frame until they release the note, much like the way they do in vanilla fnf after the weekend 1 update, but i genuinely have no clue how to code something even remotely close, doesn't help I'm not too experienced with coding in general.

any kind of help is highly appreciated, and also I'm new to this whole thing, hello!!
