hey all, i have an arturia beatstep  hardware midi sequencer that i'm trying to use with reaper to trigger drums.  i'm trying to trigger a single wav kick drum sample loaded in to rea samplormatic5000 with the beatstep, however when i activate steps on the beatstep 2 kicks per step are bing triggerd instead of 1 kick per step.   does any one know what the problem is and how to solve it?   your help with this question would be most welcome!! kind regards trey.
