shuffle plays a huge role in some of the drums i hear in recent techno records.....i can understand your problem, as i find redrum to be an awesome drum module, but for some reason (no pun intended), i still cannot get the same kind of shuffle swing feel in reason as i do on my 909 (even with the exact same settings)....
Its quite possible to do anything you can think of in redrum. Its an awesome program, but when it comes to using real drums, i prefer the 909's shuffle/flam over reasons. You can clearly hear the difference......
not trying to ignite a hardware/software debate, but its just my honest opinion.
Ohh btw, is reason the only program you are using for drums? If not, try using Kontakt in cubase or something, and draw in the notes, and quantitize to different scales......ive created some interesting patterns like that.....usually by accident :)
