To set up something basic:
click on the upper left cell, label 'C1'.
Then go over and click the file button, then bring down to 'Replace Sample'. It will open up a window to find a sample. Once you find one, click ok. Now, on your keyboard, hit every C key until you hear the sound (sometimes sequencers transpose the key up or down). From there you should be able to figure out the program.
Damn I wish Battery had a low pass filter...
At least the crossfading layers works well.
