Connect a MIDI controller to your computer using a USB cable. The MIDI controller lets you trigger synthesized sounds in the digital audio workstation as if you were playing them in real-time. This is a convenient alternative to using a keyboard or synthesizer. With the MIDI controller, you can play in drum beats, bass lines and synthesizer melodies.
Double-click the desktop icon for your preferred digital audio workstation, for example Cubase, GarageBand or Pro Tools.
Open the "File" menu and select a new session.
Create a new MIDI track. The exact method for doing so varies between digital audio workstations, but you typically execute this command via the "File" menu, although some workstations have a shortcut tab.
Type in your preferred tempo. The typical default tempo in digital audio workstations is 120 beats per minute --- that's the equivalent of two beats per second. This is slightly too fast for breakdancing. Type a slower tempo into the box where it says "120." Start at 90 beats per minute, select "Metronome" and hit "Play." The metronome will click at the selected tempo. Use this method to determine your preferred tempo.
Click on the "MIDI" track to highlight it. Open the "Instruments" menu and audition the drum sounds by hitting the keys on your MIDI controller. Once you find one you like, take no further action. The selected drum kit is automatically assigned to the highlighted MIDI track.
Press "Record" and play in a four-bar drum loop. You can either play one drum at a time, then open a new MIDI track and layer the next drum on top, or you can do it one go. The first method is more accurate, the second method is quicker.
Move the marker bar to the end of the drum loop. Right-click on the drum loop, select "Copy," then "Paste." This pastes the start of the copied loop at the end of the original, creating an eight-bar loop. Use this approach to create a drum track of your preferred length.
Open new MIDI track, select a bass sound from the "Instruments" menu and use the MIDI controller to record a bass loop. Use the cut and paste method to layer the bass loop over the drums.
