So, does drum 1,2,3, and signify the 4 pad banks. the disk I ordered has 40 sets, which is 40 programs. And, basically if I load up set 1. A,B,C and D are all basically completely filled. So, I have been loading up set 1, Make a few few tracks. Kick, snare hi hat. Then Ive been wanting to get other sounds and I keep getting screwed up. Do you think I should load up a few programs then put in a blank disc. This is main thing I am having trouble with navigating on this machine. The disk of sounds I got has 1900 samples on it. So, I have so much to choose from. I was think I should break it all down into different disks. I dont know though haha?
