Very nice drum machine with lots of features. I use it in my home studio, sometimes to record performances or just to make beats in Cubase, through usb-midi or directly to audio interface stereo inputs 3/4. I also use it live without computer and i am satisfied with results. Sound quality is very good, there are plenty of presets already installed and you can make your own preaty easily. Handling is little hard at first, you will need some time to learn all key commands and menu diving. Build quality is good and knobs are well made too, no wobling and moving, sliders are good too. Instrument pad could be a little more sensitive, so i dont need to press it so hard and more responsive. I am satisfied with purchase, its my first drum machine so i dont have much reference to compare, but like most Roland products it is very good product. Price is maybe a little to high, but it is worth it.
