I've never understood the appeal of the Nords,I had a Mark 1 when they first came out and there ok,but nothing that blew you away,pretty basic sounds and no fx either,I do like the philosophy though by remaking another version,to improve what they did before and actually naming it Mark 2/mark 3 etc instead of rebadging it with the same synthesis and trying to market it as a completely different synth and a fancy name.
They are a popular synth amongst many producers and most bands tend to have at least one on stage (if they have a keys player)
I quite like the Mark 3 but your right that the prices are very steep considering there is plenty of other choice out there and the Mark 3 has been around for some time now...
I've got a VST version of the Nord rack
well this guy likes em!!!not sure if you've heard of him???hes a french guy who plays keyboards or something!!!
