Man I love the sound of the Nord! It's raw and sounds good! A lot of modern VA's disguise the fact they sound pants by soaking the presets in lots of onboar cheapo fx NOT the Nord, it sounds great raw and also with fx...I heard the Alesis Ion and it sounds good but man I'm a total clavia freek, that thing can do techno with it's eyes closed...
You ever seen Aril Brikha on it? Check this out...this kind of gives you an idea what it's about...plus think of any good uk prog house track of the 90's...thats nord....underworld? They have two, etc etc man it sounds the shit I would get it over the alesis in a flash. Which reminds me I need one again! If you can pick up cheap also get a alpha juno 1/2 or 106/60 or waldorf pulse
