Sorry for the delay in my reply here!
I think part of the problem with this whole discussion is we are getting into the whole analog vs digital thing, and that wasn't my purpose, because I specifically said at the start of the thread " help me pick an analog poly". So TBH bringing up the whole digital thing is not really welcomed with open arms.
Anyway, what I like about the Jupiter (or any real analog) is the way the components play of off each other. For example, the filter in the J6 reacts to the different settings, whereas on the Nord it is just dead flat. Same with modulation routings etc. I also love the inherent distortions and noise in these analog instruments, and again find the Nord totally lifeless and boring.
I don't care about polyphony and multitimbrality, I have enough synths, samplers, and multitrack.
I think that banging on about the price of the J6 is unnecessary and futile. The J6 is a brilliant value for money board, and what you want to pay for one or think they are worth has nothing to do with anything. There's one on eBay now for $1,499.99, 1 bid. In comparison, I think the Nord will (has?) dropped massively in price, and represents poor ROI if that is important to you.
I am wondering what 'much more' you can do with a Nord Lead than a J6 in terms of tones, I think the J6 has more variety.
I bought the J6 exactly for the tone. If you *have* to run an instrument through processors to get an interesting tone, it is not a good instrument.
I challenge you to sit down with a Nord and a J6, and program the same tone on both, and then tell me the Nord has a better, more lively and involving tone to it.
