Adding tails to a sound.

[Works94]

I've created a sound from massive, which I recorded, reversed then chopped to create a bassline with. Because I chopped it this sound has lost a bit of its fullness and ideally I'd like to add some very subtle tails to this sound without changing it a great deal.

I'm wondering if anyone could help me to achieve this?

what about using the tail from the original?
