Good question. So when I play jazz trumpet I use the Aebersold tracks that have been around forever. I am trying to get back to being able to gig, and there are not musicians around here. On this example I am using a Boss DR-880 drum machine and a modified preexisting pattern. There are 500 internal patterns with lots of different kits, and I like the brushes since they are unique. The jazz patterns are pretty whacky and not usable. But I find one, overdub a few instruments onto it, and it is just looping a few measures. I am playing bass with my left hand live in this video and piano with my right hand. So you get the sound of an entire trio. Hard work, but you just have to think that way, a conversation between piano and drums. Thanks for your interest.
