Modulate does not work

[zecar]

repro: https://stackblitz.com/edit/nuxt-starter-ug5meav1?file=app.vue

either it doesn't work or the docs do not fully explain how to use it

from ipx github

I've tried with

modulate: [100, 100, 100]

modulate: '100,100,100'

modulate: '100_100_100'

neither worked
