Fran,
I played a Roland Discover 5 about three months ago. It happened on the store of our best friend Notlos . You are right, it is not too bad, but IMHO , I should wait for a module of Discover.....
By the way, the service of the team of the store of Notlos is very superb... Dirk is himself a great keyboardist and I had the pleasure to play with him ...Très bien...
