Thank god someone finally made a simple pattern based drum machine for the mac. I was getting so sick of the crappy ones that cost you like 150 bucks and are totally a pain to use. This thing rivels fruity loops in it's simplicity, while remaining amazingly powerfull and versatile. I love it, and I have been using it for almost every song i have made sinse i got it. The best part about it is that you can use your own samples, sounds and render as an aiff quickly. This simple little app is honestly the best standalone drum/ beat pattern maker for mac that I have found.
