Hellene - this is my 'interim' piano (yamaha ypp-55) which does not seem to fully connect with the Soft Mozart software
So I have to switch between that keyboard and the mini version for trying to learn new songs etc.
It is very old so probably that is the reason. So old that Yamaha don't seem to have the driver on their website to download!!
It is nice to play a touch sensitive keyboard but this one is quite temperamental. I am really really looking forward to getting a proper digital piano (might be a Christmas present if I am very lucky, or else next year).
