Pad Pilot is an easy to use pad generator for Ableton. It's an instrument rack that contains 3 pad sounds (organ, synth, and air) and a number of tone shaping options (filter, shimmer, reverb, pulse). However, Pad Pilot's biggest strength is it's incredible flexibility. In both session and arrangement view, you can program smooth, uninterrupted pads, drones, and pulses while jumping around from section or scene to scene. No huge audio files. No clicks and pops. Just smooth, awesome sounding pads.
