I spook too soon. I had not updated my band's iPad 2 from 8.0.0 to 8.0.2. I did so today and saw zero improvement in speed with it.
Very laggy and that is HORRIBLE for my band because this thing has to work in real-time with a Mackie mixer.
The iPad is the control surface, it replaces the knobs and sliders on a mixing console.
I guess I will attempt to downgrade it to 7x and just reload ONLY the Mackie app.
Meanwhile, my main iPad 2 64GB w/Verizon cellular is still jerky and laggy. It is also used as a control surface for our Mackie mixer (DL-1608 if you want to Google it). And while it did work at our last gig, my wife reported it being very difficult to work with (she runs sound for us from out front).
I used the other iPad (that i just updated today) for controlling our 3 monitor mixes, and it seemed "okay".
Certainly not responsive like the old 7x was.
I may bite the bullet and just reload my main iPad to 7x and spend the hours to install every app and reconfigure them. So many of these apps have no way to save their config. Apps like my video camera controllers, CCTV and Surveillance video monitors, customer tools (I work in the IT field), etc.
If I go that route, I might as well just buy a new Android tablet and configure it from scratch, it'll be the same amount of work for me.
*sigh* Apple has sure let me down.
