This is for all SD1 users .
When someone purchased an SD1 , it has 18 styles stored on the hard drive . POPDOWN1 or DANCE1 are examples . If you use these styles , a file called popdown.instr. is loaded into drum 2 of the style , which enhances the style .
The newest styles listed on Ketron's website for the SD1 , all have files attached that make them high quality styles .
