Logic Pro iPad: Modifier plugin for live crossfades?

using the modifier plugin to do live crossfades between track will work right?

I was staying away from logic and looked at AUM for live music perfomances but as i found out it wasent any logic way to make live crossfades between two sources.

so i checked out the modifier plugin and it looks really cool. I can invert (scale) and modiy to something else.

this will work for a simple crossfade right?

im on ipad and if this can be done this easy im going back to logic. It was 15 years since i used it.
