i cant seem to find some reverse cymbals and other hits that are reversed in Stylus RMX. i swear i saw them some where.
i forgot about the reverse function in the edit page.
You can reverse any sample you want in RMX.
In the edit window, create an 'Edit Group' for the sample(s) you want to reverse, then click the 'Reverse' button. All samples in the loop will play forward, except ones in that edit group, which will now play backwards.
Edit : You beat me to it
