Hello, I recently bought one of these awesome synthesiser keyboards for £25 well, I actually paid £30 as a person met me at a local train station and she bought batteries for it. I proudly owned one of these years ago and I missed having it as it has fantastic features on it. What has happened to the display? It looks like only one Half is working? Mine is in mint condition and I got the box and the proper power supply with it. I’m certainly not going to make good use of it and put it through effects and make some demos with it.
