Sorry I can't help you with the SD1 vs the SD5. Today has been my first experience playing the SD1 and it was chaos in the place. Didn't get to play as much as I wanted to of the SD1. I noticed the SD5 prototype sitting in the corner. I didn't get a chance to play it and even if I did, I wouldn't know the difference. I've played mostly Roland and Yamaha over the years. That SD1 is really dynamic. Still hoping to get many comments from present users of Ketron products.
