Hi Tony
They are 2 different kinds of boards
Sounds:
The Yamaha has the more realistic voices, but is stifled by its sound system, which gives a rounded closed in CD type of sound, whereas the G70 voices while not as accurate, have a much more live sound, which depending on what you are looking for may sound more like Real instruments, then the more accurate Yamaha. (Make sure you compare the 2 before deciding to change)
Styles:
The Yamaha gives you everything including the kitchen sink, whereas the G70 allows you to choose your own kitchen, and so again it is down to which you personally prefer. (Again make sure you compare the 2 before deciding to change)
Key Feel
The Yamaha is much lighter then the G70 and so does not suit everybody, and of course vice-versa. (Not forgetting 76 & 61 notes)
Consider the above carefully before deciding to change
Hope this helps

Bill

Thanks Abacus for your input - having everything including the kitchen sink is more me , ... a lot of the appeal too is the wider choice of styles and IDC , the G70 has served me well (it's the only keyboard i actually kept for more than a year - over 3 now!)

However ... I thought the dealer was offering me an exchange for £600 , but having chatted he was offering £600 for my keyboard leaving £1800 for a new tyros

(Although i prefer the specs of the Tyros 2 , the Roland is in the same league and not worth that kind of money - so i'll just be patient and wait for the Tyros 3 or G80)

The p/x deals seem to be v. poor these days!

Cheers

I'm not up on all internet acronyms...what does that mean??????????? p/x ..... v. ???

Dave, Partial exchange--we call it trade-in in the States.
V poor, equals very poor. The same as in the states!

Tony, if you haven't got it already, get the Session Manager software from the Roland-arranger.com site.

It blows Roland's Database Manager software out of the water, and adds radical new features to your G70, like Custom Tone storage, and batch copy of UPG parameters and OTS settings to other registrations.

It is a must have (unless you are on a Mac )

Oh, and chas... I may have only been over here for 27 years, but I always thought it was 'harbor' over here

I can't tell you how annoying it is for my spell-checker to constantly correct my 'correct' English, and keep telling me I should go to the theater, and not the 'theatre' in the 'centre' of our 'colourful' town, to 'practise' the 'defence' of my 'modelling' career

I know, I could set it to UK English, but then all my American brothers would keep going "Look at the dumb-ass... can't even spell 'ass''

Arses....

It is. Have you been hitting the sauce again. I think something slipped by you. Anyway, Tony got it. And stop reading my posts when you've got a hangover .
