I use a Samsung Tab 2 7.0....I have Band In A Box so I can make my own tracks (WAV, mp3 etc)....also BIAB will open my downloaded MIDI files and I can can edit the MIDIs in BIAB and then convert them to mp3 and then load them into my Tab 2.0....I have been doing this for a year now, works fine for me. I do a lot of solo keyboard gigs...most of my tracks are pretty lean (bass&drums) but I do use guitar, strings, and/or horns on some tracks. I don't want it to sound like a karaoke show....so as I say, I keep the tracks pretty minimal.
