Let's face it, Nord keyboards are Heavy and Expensive, and the soft case does the job of both protecting your precious unit while making it easy to lug your keyboard around.
I have the Nord Stage 88, which of course fits perfectly inside. The inside is nice and plush, but the exterior is still rigid enough to give the keyboard the support it needs. The exterior pouch is quite roomy and big enough to hold my Nord piano music stand, power cable, two 1/4" signal cables, single sustain pedal, earplugs, and still has room to spare. I haven't yet brought the Nord triple pedal inside but I'm sure it will fit as well.
The best part of the case is the wheel unit! I must admit the first time I lugged this to practice I just carried it, forgetting about the wheels. But the second time I finally wised up, and my life got much easier! A note - the wheels don't roll right if you're holding it at too shallow of an angle, so there's a handy handle in the middle of the back just for this purpose, to hold it at the right angle.
The soft case doesn't add too much extra weight (unlike the hard case), and also fits better in my car (again unlike the hard case).
You won't be disappointed.
