I have just recently purchased Spark VDM, I do not have the controller. I have figured out how to drag and drop the patterns into DP8 but the drum machine continues to play whether I drop the files or don't. There are certain points in my song where I don't want drums but it seems like no matter what, the drum machine keeps playing a pattern if my song is being played. I'm sure its a simple answer but right now I'm not sure how this works.
