JJ OS2 Note on loop function?

I can't get the sample loop function (sample loops when holding a pad set to note on) to work in JJ OS2. Where do I tell a pad to loop its sample?

The AKAI OS and JJ OS1 could do it.

Try this standard AKAI bass program: R_Bass.zip in OS1 and OS2.

EDIT: I can't find anything about it in the JJ OS2 manual.

No one experienced this problem?

Figured it out from this post
