Can't beat this for  useable drum patterns that are very configurable, after a few YouTube instruction videos.  These drum machines aren't very user friendly for anything other than changing volume, tempo, and a/b switch or pre-loaded rhythms. This is considered "outdated" but, if you do anything other than rap, funk, you will appreciate this machine.  I bought this after selling a Boss  670 drum machine that had really funky, Loud and unusual drum patterns (had great tone, clearity, rich sound) that I could never figure out how to do anything with it, other then change tempo, volume and a/b pattern switch.
