Derek Sherinian's website has a section dedicated to his studio gear setup. Two Clavia Nord Lead 3s are listed under "Keyboards." This is a keyboard Derek Sherinian uses both in studio and in live sessions. He's also an endorser of Nord keyboards. Original source [here](http://www.dereksherinian.com/gear-studio.html).more
Very clean sound quality (not an analog emulation) with an extremely flexible sound engine and the best interface I have ever used. I am very partial to good user interfaces so take that into consideration. It is great for FM-like tones as well.
LED rings around rotary encoders jump to match actual value when changed by patch load or group (eg: mod wheel or aftertouch) so there is really effective visual feedback for the current state of settings. This doesn't matter for everyone's workflow, for example if you don't change many parameters during performance, but if you do -- it's really helpful.
Has bad rep for factory patch quality vs other Nord Leads. But the inherent quality and actual capability is rather better.
