iPad live?

Hi,
I’m a newby so forgive my ignorance.
I’m looking to use an iPad live with a Fractal FM3. I picked up an iRig HD but wondering if this is the best option.
I’m willing to upgrade with a pc or Mac or whatever is the simplest to set up/take down at a show.
Thanks!!!

Either of your interface choices will work. Choose the OS that works best for you or that you already have. What are you trying to achieve?
