they are snares lower in velocity than the main snares... for example in a standard beat u got ur kick on 1, snare on 5, kick on 11, snare on 13.. u could have a ghost snare on 8 and 10 or a roll from 7 to 10, u get the idea, they just arent as prominant
Fill three or four patterns with hats, tambourines or rides on every step, then go to work making patterns in velocity, almost muting a third of the hits.
Stars are full velocity, punctuation is low velocity.
Hats: ..*. ..*. ..*.
Tamb: ..*.*.*. ..*.*.*.
Rides: ..*. ..*. .**. .*..
Read this shit strictly as examples.
Leaving the velocity spikes on different steps means the different percussive elements don't crash if they're used at the same time.
Play around with the velocity and you'll probably get more energy in your break!
