I'm feeling pretty good; I finally figured out mostly how to use MOTU BPM 1.5 and it's sounding pretty good. Some of the presets kits are a bit cheesy but it only takes seconds to morph them into formidable patterns.
I've always had some trouble with percussion but have been more comfortable with drum machines. Even though this is software, it's workflow is kind of like a drum machine. I like the sounds in Beat Thang Virtual, but this has a more sophisticated interface.
Usually making music stresses me out, but this puts some of the fun back into the equation.
