How to play it and where it comes from
The "jacking" groove of Chicago house, 1984–88 (Chip E., Farley Jackmaster Funk, Steve Hurley, Phuture): Roland TR-808/909/707 drum machine programmed from the internal sequencer with shuffle on, so even sixteenths are delayed (swing 30 ≈ 58–62% MPC style). Full, long kick on the quarter notes, clap on 2 and 4, closed hi-hat in sixteenths with accents on the second and fourth sixteenth of each beat (in velocity: 100-60-90-60), dry open hat on the offbeat, syncopated rim and cowbell as a response. The engine is repetition: no fills, just lanes muted and unmuted by hand on the machine's buttons. Variants: snare in sixteenths in the last 2 bars of a phrase (909 roll with flam), clap doubled on the 4&, "three-hit" kick (x..x..x.) in tracks closer to electro. For acid house, add the TB-303 line in sixteenths with accent and slide.
