Here is a video showing how to get led feedback when using the Akai APC20's note mode with ableton live, similar to native instruments' maschine. You want to set you transient ( warp ) markers on your audio track, right click and select "slice to midi", select transient as you slicing option, arm the new midi track and play you pattering using note mode. Then add another midi track and route the midi from the midi track with the slices out to the apc20 on channel 10.
Also leave the "monitor" option set to "in" on the midi track sending the midi out to the apc.
