Personally, I rewire reason in to Cubase specifically so I can manulipate rex files. The rex player and the grid sequencer is f***ing amazing to me.
Oh damn, I figured this problem out once and I have forgotten how to do it. Let me ave a go when i get home and see if I can remember. Maybe you should try doing this without converting the audio to a part? Theres deffinatly a sequence on how you should do this. Try calculating hit points in the audio editor and then b4 you slice it up with the divide audio events press the "Create Groove Quantize". That allows you to extract the groove of the hitpoints into your snap area. Very interesting results can come of this.
