I just want to add that if you are thinking about buying a G-70, wait! First of all, just because the G-70 sounds better than the Tyros in some basic sound categories it doesn't necessarily mean it sounds good enough. To tell you the truth, I would never buy the Roland G-70 myself. As I already said the G-70 is quite and less cheesy in the rhythm element, which makes it easier to process on a recording so that you end up with a good result, unfortunately the price to pay is rather high and this is I think the really interesting thing in the context of these keyboards and the Tyros 2.

The Tyros 2 has a voice realism no other keyboard has, that's simply just a fact. It takes a professional to get it right on a recording though. When comparing each sound category the Tyros will win in most of the categories. Its guitar sounds are absolutely fantastic in comparison, the same with the sax. The drums are among the better, the electric pianos too. The acoustic piano, from what I've heard, is not very impressive, but then you have a whole range of really good sounds like flutes, strings, brasses and some good organs too, all of them compensating well for the bad acoustic piano. The organs and the acoustic pianos are clearly better in the Roland G-70 (from the sounds I've heard). Now, when thinking about its expansion features I think the Tyros 2 becomes very interesting in comparison. Here you have a keyboard that has the best realism in a lot of categories with the chance of getting great sounding rhythm elements some day too...! So I would really choose the Tyros 2 before the Roland G-70, any day...

Instead of going for a Roland G-70 I would choose a good Roland synth instead, that's because you get more rhythm element sounds for the money. You get a clean low end. You get a professional vibe in another range, you don't get any better acoustic piano sound or organ, but you do get better basses and drums! When it comes to a really good sounding low end, for instance bass and electric piano, the Roland IS the winner of them all. It is deep, clean and quite. Comparing that with the low end of an acoustic piano sound in the Tyros is just like night and day! This clean low end is very useful on a professional recording! It doesn't necessarily need to be audible as long as it is there somewhere. What you would normally do with the electric pianos of the Tyros would be to apply a high pass filter just to clean up the low end. You would also turn down frequencies around 400Hz and 800Hz to minimzie the cheesyness. But I think many would really like to layer some low end of the Roland instead just to make it deeper sounding in a clean way, because you want clean frequencies down there when you start mixing for depth with an EQ effect on those frequencies.
