Hello Squeky,
Yes , the X1 is truely an amazing keyboard .Soon the SD1 from Ketron will be available .
The navigation is completely different on the SD1 vs the X1 . The drums on the X1 are above average. With the SD1, Ketron added vocal drum kits . Very human like sounds. Like TAKE SIX or Bobby Mcfarland ( not sure if I spelled that correctly ) . I think I could create a "Don't worry be happy " style . Can't wait ! Dan O1
