You need to make a 1 bar midi track with a note on each beat, and send it into a sampler. load up a click noise, beep or sticks. take your midi event and copy it. paste it into the next bar. do it again until you have 4 midi events side by side. select those, copy and paste them side by side. now you have 8. select those 8 and paste them again. see where I'm going? do this for the entire track.
If you have tempo changes in the song, the midi will still reflect that.
then just mixdown
