Alesis iO Dock II

Hi everyone, I have tested the Alesis iO Dock II with :
iPad Air 16GB, Planet Waves cables, Rode NT2A, Musicman JP custom with Dimarzio (Norton,Air Zone), Casio CTK-571 (controller midi) , Behringer FCB1010, MIDI 5 DIN cabel.
Apps: GarageBand, JAMUP + BIAS, Amplitube, Sampletank
Sound: Guitar - Line 1 input switched to guitar mode - Little noise, Feedback in High Gain sound (gate,filter must be used in chain) , Complete round trip (Latency) in ,,low latency mode,, its around 15ms so if you played little bit faster, you can feel it
NT2A - Phantom +48V worked, but push lvl of noise high, for DEMO record its fine, but definitely not ,,professional,,
MIDI: Keys worked pretty well, no latency. Behringer FCB1010 worked in real time in JAMUP with Whammy, Wah very well too... you can programing presets, stompboxes, recorder, sampler.

For those who want to feed a midi controller on IODOCK, please have a gender changer (http://www.computercablestore.com/USB_Adapter_USB_A_Female__PID49988.aspx)
USB Adapter - USB A Female to USB B Male.
The big square toe connects to IODOCK and USB Port flat supply power to the master controller or keyboard or MASCHINE.
For more handymen take a look at this video, it is certainly a solution, but what do you know:

On paper, the product met my expectations. The idea was to make me a little mobile studio for the holidays. The real plus of this resort is that you can power the iPad while registering then with a mobile interface as in the line 6 we see the battery level off at high speed and you must always remember to reload ipad.

Or there is great disappointment is that the guitar input produces a very audible hum whatever guitar and whatever settings. It is therefore useless to record a guitar. Latency is also audible, but still manageable. I do not know if this is a fault of mine or related to my ipad 2.

I turned my stuff and I try something else.
