Ultrabeat Issue

When I drag a pattern from the Ultrabeat sequencer to the region window, not all of the sounds are heard and the beat seems to be changed. By switching Input Mapping from GM, to UB, to C1 and dragging the pattern into region again, I can get different sounds from the beat to play, but can't get them all to play together properly as they do when I press play on the sequencer. The outputs of all percussion sounds are set to "Sub 1."

I'm using Logic Pro X on a late 2009 iMac 21.5" with Yosemite 10.10.2.
