All i mean is that if the response of a virtual fader is delayed, that is not a deal-breaker. But when you are trying to record midi and there is a delay, a good performance is virtually impossible. Low latency monitoring of an input signal is where android's lmitation lies . I recent;y got a Galaxy Tab 2 10". and although it's a an awesome tablet, it can't play a piano or drum app without a noticeable delay and it can't record a stereo input in it's 1/8" jack- just mono. These are deal-breaking issues for audio and midi recording. But John above put a link to an audio mixer/editor that looks really cool. I'm looking forward to checking that out.
