If you're looking for some great beats to rap over, of just want to add a few realistic drum sounds to your music, look no further than a Roland drum machine.
I've always been a big fan of the MC 307 which has some great electronic sounds and is usually available on eBay for quite a good price.
*Pro Tip* The biggest thing I have leaned over the years when buying this type of equipment, is that as soon as you bring it home the value is cut in half. So now I buy everything secondhand after the value has already decreased;-)
Just to let you know, I've been using the Roland drum machine for around three years so I should be able to give you an insider view before you buy.
You probably already know this but Roland not only produce great beat machines but also put out a massive range of quality musical instruments as well. The instruments are now thought to be among the best in the world. This means that you can feel confident you're getting the market leading beat creator for your music. I think it's safe to say that the Roland drum machine is the best in the world right now.
I do have to let you know that using a beat machine is quite old school and can be fiddley to get your head around. A software program like Reason would allow you to get all the benefits of using a Roland drum machine, but give you much more flexibility and ease of use when it comes to editing. Although for me a beat machine has always been the way to go because you can get your hands on it, and it will never ever crash when you're out playing live!
The best thing about the Roland Drum Machine is the sounds, no other piece of gear will give you such a massive range of really nice beats and loops. There is nothing worse that hearing a really good track that is full of rubbish sounds. It makes your music sound really bad, so either jump on eBay and pick up a Roland drum machine, or go for the Reason option.
