Trap Hi-Hat Patterns: How to Program Rolls, Triplets & Bounce (+ MIDI)

Trap hi-hat MIDI patterns with rolls and triplets

Melodies get the attention, but hi-hats are what make a trap or drill beat move. Rolls, triplets, bounce, pitch-ups: a good hi-hat pattern turns a simple loop into something people nod to. Here's how to program trap hi-hat patterns in any DAW, step by step.

1. Set the tempo and the grid

Most trap sits between 130 and 160 BPM, felt in half-time (snare on beat 3). UK and NY drill usually sit around 140–145 BPM.

Set your piano roll grid to 1/16 notes to start. You'll switch to finer grids (1/32 and triplets) for the rolls.

  • Ableton Live: Ctrl/Cmd+1 and Ctrl/Cmd+2 make the grid finer or wider, Ctrl/Cmd+3 toggles the triplet grid.
  • FL Studio: in the piano roll, use the snap menu: Step = 1/16, 1/2 step = 1/32, 1/3 step = 1/32 triplets.

2. Start with a simple base pattern

Every great hi-hat pattern is built on a steady base. Two classics (one bar, 16 steps, x = hit):

8th notes  : x - x - x - x - x - x - x - x -
16th notes : x x x x x x x x x x x x x x x x

8th notes feel laid-back and spacious, 16th notes feel busy and driving. At 140+ BPM, 8ths are often enough: the rolls will do the rest.

3. Add rolls (the trap signature)

A roll is a quick burst of hits that fills a gap. Replace one or two hits of your base pattern with faster notes:

  • 1/32 notes: two hits in the space of one 16th. The most common roll.
  • 1/16 triplets: three hits in the space of two 16ths. Smoother, more "rolling".
  • 1/32 triplets and 1/64: very fast "buzz" rolls, best kept short (one beat or less).

The golden rule: don't roll everywhere. Place rolls at the end of a bar or a 4-bar phrase, right before the snare, or to answer the melody. Contrast is what makes them hit.

4. Use triplets for bounce

Switching from straight notes to triplets for one beat creates the famous trap "bounce". Example over one bar:

  • Beat 1 and 2: straight 8th notes
  • Beat 3: 8th-note triplets (3 hits)
  • Beat 4: 16th notes ending in a 1/32 roll

Change the position of the triplets every 2 or 4 bars so the pattern never feels like a loop.

5. Shape the velocity

Hats that all hit at the same volume sound robotic. Work the velocity:

  • Accent the downbeats (100%) and lower the hits in between (60–80%).
  • Make rolls fade in (crescendo) or fade out: draw a ramp across the roll's velocities.
  • Add a little randomness (±5–10%) for a human feel.

6. Pitch your rolls

A classic trick: pitch the hi-hat up during a roll, by 2 to 7 semitones, then come back down. It adds movement and excitement. Move the notes up in the piano roll if your sampler maps the hat across the keyboard (FL's sampler channel, Ableton's Simpler in Classic mode), or automate the sample's pitch.

7. Add open hats and layers

  • Open hats on the off-beat ("and" of 2 or 4) add groove. Put closed and open hats in the same choke group so the closed hat cuts the open one, like a real drummer.
  • Layer a shaker or a percussion loop, quieter and slightly panned, for width.
  • A touch of swing (10–20%) works great for R&B and afro, less for hard trap.

Drill hi-hats: what changes

Drill hats are more syncopated: fewer steady 8ths, more gaps and off-grid triplet groups that bounce against the sliding 808. Program a pattern, then delete hits until the groove breathes. Keep rolls short and sharp.

Common mistakes

  1. Rolls in every bar. They lose their impact. Save them for transitions.
  2. Flat velocity. The fastest fix for robotic hats.
  3. Hats too loud. They should sit behind the melody and the snare, not on top.
  4. The same bar on repeat. Change one detail every 2 or 4 bars.

Skip the clicking: use hi-hat MIDI patterns

Programming every roll by hand takes time. Hi-hat MIDI files give you ready-made patterns (rolls, triplets, bounce) that you drag onto your own hi-hat sample, then tweak. Same idea as melody MIDIs: the notes are done, the sound is yours. New to MIDI? Read What Are MIDI Files?

How to import them: in FL Studio or in Ableton Live.

FAQ

What BPM are trap hi-hats?

Trap is usually 130–160 BPM in half-time. Hi-hats run on 8th or 16th notes, with 1/32 and triplet rolls on top.

How do you make hi-hat rolls?

Switch your grid to 1/32 or triplets and replace one or two hits with a quick burst of notes, usually just before the snare or at the end of a phrase. Ramp the velocity and pitch the roll up for extra movement.

Can I use hi-hat MIDI with any drum kit?

Yes. A hi-hat MIDI pattern plays whatever sample you load, so it works with any kit, in any DAW.
