Do you mean Reggae as in Roots Rockers or Dancehall?
For Dancehall you can refer to the other thread. What makes it a bit easier with (later) Dancehall beats is that they're usually made with drum machine/sequencer.
Old skool reggae is a quite different thing. It's usually much slower, with a more relaxed and 'human' feel, less machine beat and best played with 'real' instruments. Just for starters, if you take a very simple 16 step pattern for reggae you would get something like this:
BPM 60-80
HhHhHhHOHhHhHhHh
K---K-------K---
----R-------R---
--C---C---C---C-
H = hihat with accent
h = hihat
O = open hihat
K = kick
R = rimshot or snare
C = chops
There's a lot of subtle variations going on in the hihats, especially in velocity and open/half open. You can also experiment with a slight shuffle on the beat. Or a faster straight 8th feel like in Bob Marley's 'could you be loved'.
Anyway THE thing in Reggae are the chops and a nice deep rolling bass line.
