Roll Or Delay Effect?, I'm going nutts? Options

[Vastworldwide]

Ok, I'm going to try and get this out into words as best as I can?
I have a track done. The only thing I want to do to it is:
In some spots I want to add like a Roll effect to the entire track.
Not a drum roll but almost like a flam effect to the song ina whole.
I know on drum machine (hardware ) there are the pads loaded with intruments. then there is a roll button where you can hold thr roll button and the pad of your choice and it creates a delay effect. I wish I could put this into english but i'm tring? Does anybody know what I mean? I have Logic 7 and reason, can I do this some how? I have a feeling I'm going to need to buy something.

If I could load my track into a drum machine with the roll feature that's what I'm looking to do. take the whole track and put in like 2 second rols every once in awhile

If you understand this jibberish, please help
