Hellow everyone.
I'm at the point where I'm about to buy a synth, but I'm not sure which one to get.

I'd like to be able to produce sounds similar to Eiffel65.

The synths I'm looking at are

1) Nord Modular (rack)
2) Trinity rack
3) Roland JP8080
4) Novation Nova

I'm really leaning towards the Nord Modular, but I don't know how easy it would be for me to program sounds since I really don't know much about synthesis. Also how easy is it to program the modular without the computer?

Any comments would really help. Thanks.

Nord Modular will definately keep you going for some time.
Also consider and check out the Access Virus, got one and love it.
