SampleTank iOS + iReal b

The iRig midi interface has just come out and I’ve been using it to connect
a midi keyboard to my iPod touch (4G, iOS5). Latency is very low and
a few of the SampleTank pianos sound good when mixed with an iReal b
backing track! (setup instructions for Amplitube apply)

With so much processing going on iReal b will sometimes skip a beat.
It might work alright on an iPhone 4S or iPad 2.

The reason why some SampleTank pianos don't play well with iReal b is probably due
to sample size. But this setup is about as minimalist as you can get.
