It won't take too long to figure out everything involved with this keyboard as even though there is a lot going on, it is laid out in a convenient way that is easy to understand. The feel of the keyboards also is very realistic and is overall an easy instrument to play. The manual for the Clavia Nord C3 is thorough and would be helpful to have around when learning this especially if you don't have any experience with organs.
The Clavia Nord C3 does a great job of emulating organ sounds all across the board. I use it mostly for the Hammond organ sounds that it is so great at emulating, but also love the Farfisa and Continental tones that are available on this versatile organ. The sounds are overall extremely realistic and unless you have the real thing, I haven't heard any emulators of any of these classic organs that comes as close to the real thing as this does. It has a ton of control available over your tone and the reverb, delay, and amp simulating effects are all top notch. I can't think of anything bad to say about the sound of the C3 as it is just a stellar instrument.
I first used the Clavia Nord C3 about a year ago and I was instantly impressed with the palette of organ sounds made available within this single instrument. This is a perfect organ for those who want to get all sorts of organ sounds during a live show or even for recording if you don't have access to the original instruments that this emulates. The price of the Clavia Nord C3 is certainly expensive but is aimed at those who are looking for great tone regardless of price. If you are looking for one of the best digital organ emulators around, the Clavia Nord C3 is just as good as any.
