For midi input, low latency is essential and latency differs for each tablet.

From the devices I've tested,  Gallaxy Nexus and Nexus 10 were the best

so I couldn't feel delay.    Nexus 7 1st generatioin was second best and

I could feel a little bit delay.    And next good one was Nexus 7 2nd generation,

on which I could know there exist some delay.    I've tested Gallaxy s3 but

it has much delay so I think it may not be practical to play on the devices which has

same or more delay than s3.
