I have iPad3/iOS8.1.2/MF3
Whenever I start MF for the first time, the EQ, dynamics and quick access panel all take about 4 seconds from the tap for the screen to come up
After the first time, the screens come up fairly quickly, even if its a different channel
The faders and output selectors seem responsive right out of the gate.
EQ screen seems to be the worst. Not only is it slow, but its hard to take your finger off the screen without it jumping to a new spot when you do this
Another thing I noticed is that when I start MF3, it always comes up disconnected. I have to manually attach to the DL each time I restart MF3
I'm pretty sure that MF2 used to just synch automatically to the DL, although I could be wrong about this. Prior to MF3, I didnt spend much time closing and reopening MF
