the shop i went into had the korg pa1x , the tyros and the G70. The tyros and G70 do not have built in speakers and the korg does. I tried all three through the same mixing desk. I am not a technical person when it comes to setting up demos with equipment i am unfamiliar with but the store owner who helped set up the mixer and amplification is. The Korg quite clearly sounded better simply in tonality and fidelity. You will find a common theme with posts about the G70. The sounds straight from the box have far too much effects on them. So eg the piano sounds like you can here it in a large room from a distance. That was just one example and unfortunately there were many. If you like latin styles do not spend £000's on a keyboard simply for that.Styles are easily bought on the net or provided freely from other net resources with a little tweaking. But i would suggest that your focus should be on the actual quality of sound and usefulness of the keyboard features. I focused on the sound. To me thats the selling point of any musical instrument. Value for money is important and functionality but thats not the primary concern. If it were i would buy a casio ( I am just creating enemies left right and centre here...no offence to casio owners!!) What i am saying is that you need to try out these boards yourself if you can find a distributor and make up your own mind. But as a consumer and a genuine potential buyer of Roland products, Roland are making it too hard for me to find something to like about the G70 right from the outset. And from what i have read , by limiting its distribution to certain outlets , they are making it difficult to actually buy their products too....
