The SD1 is a marvelous keyboard. The sounds and styles are quite good. My customers love this keyboard, but they are also complaining about the difference in the way the features work compared to other Ketron products.
So far, disk management seems to be the biggest complaint from former X1 users who have upgraded to the SD1. I have not had any SD1's freeze or lock up to my knowledge. I'm sure my customers would call me if this was a problem.
Where I do see a need for a lot more explanation is in the area of disk management. The way you select and load styles from the master folders style folder is very confusing. I have been able to show and explain how to call up disk styles but I don't completely understand how and why certain things are happening and this is frustrating at times. I'm sure this will eventually proove to be a very convenient way to call up and play styles, but It's really not clear to me or others yet. I've gone to the pattern copy page where you copy parts or all parts from one style to another, but I have not understood how to choose a destination location other than number 1 in the style folder, and when doing this, I substitute what was originally in location one (example: dance 1) with the style I am selecting as the source (example: slow rock). At this point, dance 1 now sounds like slow rock and I have lost dance 1. I've gone into every folder on the SD1 and i can't find the original dance 1. I don't have this problem with the X1 because all patterns are loaded into pattern locations which are seperate from the patterns on the hard drive folders. On the SD1 the patterns are always in the hard drive folders and never in a seperate pattern memory area (I think) and so when I lost the dance 1 pattern, it was lost forever because it wasn't saved in two folders, only on the one. I don't know if anybody understands this, if I made any sense, but this is something that Ketron really needs to explain to the end user and to dealers in much more detail.
