Audrey the KN7000 is getting pretty old now and although it was ahead of its time when it came out and nothing in my opinion could touch it but alas like all things time marches on and the kn7 when they go wrong now it is hard to get bits particularly for the board circuits. Before you go back down the kn route try and check out the Korg PA 800 or if the budget is a concern the PA500 A PA600 has just been launched. They are all absolutely full of surprises fantastic sounds and very user friendly, very light. In my opinion it is the nearest I have been to a kn7 since I had one. The biggie is they come in at under £1000
