Is it possible to install Audio Unit Extensions (AU Extensions) to Garageband for Ipad?

Hi Apple Friends,

I have an Ipad and I have downloaded the latest version of garageband (the version they released in Q1 of 2016). I would like to know if it's possible to install or use AU Extensions in the ipad? A similar case would be like in Garageband for Mac where you load Roland-Like-Piano-Audio-Effect and when you use external instruments, it sounds like a digitally mastered audio 🙂 please if anyone can help, thanks a lot!
