I was playing a wedding reception here in Montana and the father of the groom visiting from Clevland said he had a G70 and asked if I was using ver3. I just got the G70 a couple of months ago and I am still figuring it out so I haven't tried and additions to it. Here are a few questions: 1 Is it worth putting on, 2 Is it hard to install. 3 Why isn't it on the Roland website I have only seen it on the Danish G70 club site. Lastly it is so cool to meet someone through a keyboard and have so much in commom because of keyboard websites. This is the second SZ person I have meet one in Connecticut and one from Ohio.
