4. Groove considerations
Unless the elements of your song fit into a sonically pleasing groove, your stuff is not going to "hit" properly. Masters of hip hop beats are masters of groove, and can lay down a drum pattern with no correction. Most of us have not perfected this skill, so we use quantize templates to achieve the right amount of groove and apply it to our tracks. You might note that your sequencer already has built in grooves that can be applied to any midi track. Grooves that work well with hip hop are based on 16th notes with a swing value in the range of 57-83%. 50% is straight 16th notes. 100% pushes the 16th note to the next 8th note. 0% pushes the 16th note the the previous 8th note. As you pass 57% you will hear the groove start to relax and as you reach around 70% you are in classic hip hop/rap territory.

Another method of getting a hip hop groove: Quantize the kick drums on a 24th note quantize divisor and the rest on 4th, 8th and 16th notes. Why 24ths? There are 6 values between quarter notes on a 24th note grid. They all groove in a nice way when offset against claps on 2 and 4. Try to avoid putting a kick on 2 or 4.

Try this groovy tip.
Start a drum pattern with claps on 2 and 4 and a kick at 1 and 3. That is standard 4/4.
Now, set the grid to 24 and add 1 more kick on the grid, anywhere!
Press play and listen. Move it till you like what you hear.
Then add a 4th kick and move that around. In the process you will hear many different hip hop groove possibilities.
5. Move to Microscopic editing (next)


5. Microscopic editing.
a. MIDI. Your sequencer has an offset parameter. This moves all the notes you highlight by midi ticks, the smallest possible note division the sequencer is capable of. If you tried the above tip, now grab all the kick drums except the ones on 1 and 3 and offset them by a few ticks in either direction. Listen carefully for a head nodding groove. Copy the drum sequencer to a groove template (read the manual). Apply it to the bass. Mind over groove. You are there.

b. Audio If you put a common audio loop on an audio track in the sequencer and slice it into parts, you can apply destructive editing to each part in an audio editor. You can move these "regions" around, delete some, stutter others, and if the sequencer allows, re-groove the hits and save to a new audio file. For those who are into making esoteric beats, you can borrow elements from one audio loop and precisely place it in another with simple copy and paste commands.
