Hey dreamer, you are right only time will tell. They were the same in the SD family, whether you had an sd5, sd2,midjayplus, the sounds for the arranger were the same. I was told,someone who was contracted by Ketron, the sd1000 will be the same as the Midjaypro in terms of sounds and percussion for the the arranger section. After I read your comments, I texted him for further detail to make sure. I am hoping they are the same,since all I want is the arrager section. The Sd2 had all the ingredients one needed the recipe (software).
