All you need is a computer or laptop with software like fruity loops, or cake walk to start making banging hip hop beats and drums kits. First, find you a great beats library to download. You can check out the resource box for recommended sites.
Next you will want to set your music software to accept mp3's, wav files. Most samples will either be mp3 or wav and the software, in most cases will convert the file for you.
Once you have preview the loops or samples you want to groove with, try cutting three to four different samples to create a drum pattern or beat loop.You can do this by dragging the file to your edit window inside your music software. Take your editing arrow and cut the beats into 1/4 time signatures. Listen to the beat, if you like it you can consolidate the chops to make one solid music file. Or you can keep playing around with different time signatures like 1/8 or 1/16.
You'll be really surprised at how this process can really get your creative juices flowing. You can also use the instrumentals for song writing ideas. Music loops and instrumentals are a good source for songwriters. Last, make sure you have proper license to use the beats for your projects. Do not go full throttle without taking care of your business first. Most beat websites have their license requirements on the website.
