proper loop sample with backward enabled

How can I clean loop a sample where I activated the <--> option in the trim section?
I tried the audio track, but this ignores the backandforward option.
I also did a step edit and but this didnt work either, since I cant exactly find the right time.

thx

i don't understand your goals here...try to be more thorough and i'll help you out, alternate loop is among my most frequently used features.

is the pad on "note off", in "params"?
