Since I already use a lot of instruments on stage (SPD-SX pad, organelle, Nord Stage 3 with effects pedals) I don't want to add extra shitload of electronics and materials on stage during the shows. So, let's say I'm looking for the smaller/more practical/easily mobile setup.
Thinking how I would go about this if Komplete would enhance my performance on stage and would make the audience faint with anticipation as nonchalantly grab your iPad, I would probably start with a Mac mini or compact PC thingy (sorry but I don't know what the correct name is but a PC in a tiny box like a Mac mini).
Simple life is a small laptop and something like a WD passport drive with all the libraries on, you could even do the Jump Desktop stuff with the laptop if you wanted to use the iPad on stage. Requires a little work but at the end of the day it would do exactly what you want.
I am referring to the fact the post from Mistertoad17 is simply a different suggestion which he has taken some time to offer from his own experience and nothing I read in his answer is wrong at all, maybe a little different/complex for the application but it IS a solution and one I have used myself before, just fine, tho not on stage. You can sit an ipad on the keyboard to simply use it to do some of the stuff you need a computer for without having a computer on stage, just to make it look more professional, I know of others round here who have also done this kind of thing.
All your messages completely answered my questions. I don't mind experimenting and trying stuff to get the results I want, but I get that the easiest/rational/practical solution indeed is the smallest computer possible and a sound device on stage. Also, it fits with my knowledge of computer science and my will to keep music as much as possible to the instruments more than to technology ;)
