OK Steve,
Fill me in… THIS is what I am pretty sure I need also. I have ONLY cover that I play and record for my own enjoyment ALTHOUGH, I did loop a few things together and then added my own audio guitar lead and fills to those looped tracks. Frankly, they came out pretty good as those loops keep good time 
When I need a drum pattern that I can play my self, I can get it to do exactly what I want. So are you using one of those electronic drum pad kits? I saw a few under $750.00 that look pretty good but I had’nt planned on buying any as I still was not sure this is how to go about it. I’m no Ginger Baker but I can keep a reasonable rythym going …surely enough for my recordings
