my first synth so which one should work for me better? I'm mostly interested in house/dance music and maybe using it as a midi controller also. anybody has experiences with these and would be great if I could get some pros/cons about both. tnx

Vape,
These are really different synths, as far as for dance/house they would both be good, you will get fatter sounds off the nord, but the triton will be more well rounded. You'll have a good sesction of everything you need. With the Nord you would most likely want to also get a drum machine, hardware or software, and a sampler, as the nord is more of a dedicated synth, bass and leads/pads.

tnx for the reply.

I came upon a Roland SH-32 and was blown away. Those other synths are great, but for the blowout price of $199 they go for now, consider the Roland for your dance music. It has an great synth engine. It's somewhat muiltitimbral (4 pasrts) and has a very cool (user programable and preset) arpegiator for drum or synth sounds. . . . and lots of knobs. Totally midi syncable... Also good effects. I love mine. By far the best value I've gotten in a synth.
You don't want it as your one and only or first perhaps, but it's a great addtion. I don't know why these didn't catch on....
