What's the best drum machine?
Currently, the most amazing, most mind-expanding, beat processing, pattern battling drum machine on the planet is the Pulsar-23 from Soma Labs, no, hang on, it’s the Perkons from Erica Synths. These two are amazing and like nothing else on this list or anything you’re likely to encounter in hardware or software. Does that make it the best? Yes, from one point of view. But if you want something a bit more traditional and less “out there” then check out the Roland TR-8S as a fabulous all-rounder.
What's the easiest drum machine to use?
The Roland TR-808 was one of the first and most straight forward drum machines to be invented. It dominated the music scene of the early 1980s followed up by the TR-909 at the end of the decade. Both of them are very easy to use and many later drum machines were based on their button/step format. Currently Behringer offer clones of these classic machines in the RD-8 and RD-9 both of which are superb.
What drum machine do rappers use?
This depends on your era. A lot of early Electro music was ruled by the TR-808 and then 909. In more recent times beats have flowed from the Akai MPC range of drum machines. But don’t be fooled into thinking there’s only one way to do something.
