The SD2 NEEDS to be tethered to a computer. I bout the (much more expensive) SD4. I had the Roland for a week or so, but put it up on eBay. It is a more versatile box, but you can't beat the acoustic sounds on the Ketrons. They simply sample better musicians playing better instruments (what a concept?) RealTracks mitigates the thythm section, but for playing melody and solo with MIDI the Ketron rules.
