I've been wanting to be able to tune my 6to8 without going out and buying a new windows-based tab. I already have a laptop that I've been using, but it's a PIT to hold while messing with it,and the Android app that Mosconi has is basically useless.
I found an app called Jump Desktop which allows me to remotely control my laptop with my Android tab. So basically, I set the laptop near the DSP, and I use the tablet to control it. So far it works like a charm.
