When I heard Mac's SD2 demos a few years ago, I immediately got one and haven't been disappointed. I've tried Aria and other soft synths (from Sonar X1). None compare with the SD2 that I've tried and it's very easy to use the SD2 with Sonar. The only button on it that I use is the power switch. Very simple to use. FWIW
