Hello i started this topic : Ipad/iodock2 or Blofeld Waldorf for live?
So now i am thinking of the ipad solution for a cheap polysynth…
But do you guys use it in Live situation with a Alesis iodock ( for exemple ) and midi cc controller ( my octatrack in my case …)
Thanks a lot for your input 
I’ve run the following live without issue ( apart from forgetting to recharge the iPhone battery):
Audio:
audio in > uca222 > USB hub > cck > iPhone running Loopy > uca222 > audio out
Plus midi:
Rocktron midimate > cheapo USB midi cable > USB hub > cck > iPhone running Loopy
The key for me was always putting the phone in airplane mode then hard rebooting. This clears the cache and ensures you don’t accidentally get a phone call through the PA. You might also want to check out the audiob.us forums as there are a bunch of people who use iOS live over there.
I finally bought the last ipad ( 5? ) and it s really working great with model 15 very stable and great sound !!
