Hi there,
and welcome to the somewhat exclusive Noah club.
Don't worry too much. The sound palette you get with the Noah is fantastic.
The less immediate ones like the Vecton, the Lightwave and espescially the 6-Strings are just as inspiring as the fantastic classics. It is not only that the sounds and the presets are great. The Creamware models are extremely expressive and begging to be played musically (Mod Wheel, Aftertouch, velocity).
Much of the music I did in last few months is largely based on the Noah.
Here it is:

Have fun !
