I found a neat little free VST Drum Machine plugin today called Grizzly. You can download it here: http://www.majken.se/index.php?option=com_content&task=view&id=6&Itemid=9
I was recording some “cheers” for our VBS this summer and needed something that I could easily create a decent sounding drum beat in. This little plugin worked great in Reaper and didn’t take me (a non musician) long to figure out. My only complaint is that the text in parts of the UI is way to small too read.
