From Particulars manual (which you can find by presssing the “options” link inside particular then pressing the “help” button inside options:
****
The Split Clip modes splits the custom layer into a number of clips given by the parameter “Number of Clips”. For example, if the custom layer is 30 frames and “Number of Clips” is set to three, that means it will be split into three 10 frame clips. This is useful for creating a set of animated particles.
Split Clip – Play Once Randomly select one of the clips and play the clip once.
Split Clip – Loop Randomly select one of the clips and play the clip looping.
Split Clip – Stretch Randomly select one of the clips and time-stretch it to fit the particle life.

So if you have a clip 150 frames long divided as follows: 1st a triangle going slow for 50 frames then another triangle rotating medium for 50 frames then a third triangle rotating fast for 50 frames then choose “split clip loop” and then set “# of clips” to 3 — Particular will emit three different triangles each rotating three different speeds — more triangles — more # of clips and you can have 20 different speeds if you like (I think?)
Does this help??
