Can I install and use logic Pro X in iPad Pro?

No, you can't, sorry. To my knowledge, Logic Pro X is for macOS devices only.

On your iPad you can just download Logic Remote iOS app, this one:--> https://apps.apple.com/app/logic-remote/id638394624

Plenty of very good Multitrack DAW apps in the iOS App Store.

Many of these will be paid apps, though.

Just look in the iOS App store for Multitrack DAWs.

Also, looks for DAW apps that are Audiobus 3 compatible.

Also, many software sound modules that are, also, Audiobus 3 compatible for iPads.

Audiobus 3 compatibility is needed for all of these software sound apps/modules and software DAWs to wotk seamlessly together.

You'll also need to pay for and download the actual Audiobus 3 app from the iOS App Store, as well.

These work with Lightnng port equipped iPads with proper adapters and external power source and work with iPad models with USB-C connections.

I have quite a music setup on my 2015/2016, 12.9 inch screen iPad Pros.

Lots of apps/software to choose from.

De rien :)

Definitely NOT!

Look at LumaFusion for iPad/iPadOS.
