The RD-2000 has exceeded all of my expectations. Action: I purchased the RD-2000 primarily for its action. I also play a baby grand piano regularly and the feel of the RD-2000 is so close that it is a pleasure to play with minimal adjustment. For those not accustomed to an acoustic piano it may feel heavy, though perhaps adjusting the Key Touch to a lighter setting may help. Sounds: I was sold on the RD-2000's VPiano sounds. Plenty of digital pianos do just as good a job (or better) at reproducing a single note played in isolation. The RD-2000 shines when you play it as a whole instrument. When you play an acoustic piano it sounds like more than just the individual notes due to how the strings interact with one another. The RD-2000 reproduces a lot of that feeling. One thing that really surprised me is how much I also enjoy some of the other sounds: the vintage electric pianos are very rich, the bass sounds have a very solid realistic sound. Even though I bought the RD-2000 primarily as a piano and was going to use a DAW for everything else, I can see myself incorporating more of the RD-2000 sounds. For those not using a DAW, the RD-2000 has a respectable collection of strings, pads, leads, synth brass, etc. Controls: there are a lot of buttons, knobs, and sliders. Adjusting the effects is a breeze - much more intuitive than with instruments that force you to edit every parameter via an LCD display. And since it is easier, I find myself exploring and tweaking the settings a lot more than with other instruments. Program and tone selection is simple and fast. The zones are flexible and once you have them set up the way you want switching active zones is just a button press. Overall this is an amazing instrument.
