DC offset won't put a click in the middle of your sample. DC offset is a shift of your ENTIRE sample up or down...this can cause clicks at the beginning or end since the MPC's DAC's are at zero, then suddenly jump to the first sample point of your sound.
Clicks are high-frequency..like a sudden jump from full-on to DC in a very short period (ie-1 sample point). If you trim your sample, and AFTER the trim happens, you have 2 sample points that aren't near each other vertically (zoom all the way in to see it) ...you get a click. Zoom into the point of the sample where the click is occurring...I bet my MPC that there's 2 points that are vertically unnaturally far apart from each other. When you do your trim, make sure you do it clean. It's the same concept that zero-cross detection does for looping.
