Trap Hi Hat Patterns

Trap hi hat patterns start as straight 8th notes at 130–150 BPM and get their bounce from rolls: one beat broken into 16ths, 16th-note triplets or 32nds, with velocity that climbs and falls. In Veena, a free AI DAW with a personal music producer built in, CoProducer writes every roll into editable MIDI, and you shape each hit on the Beat Maker grid.

Trap hats sit on a dead-straight grid. The triplets do the swinging, which is why the same four bars can feel stiff or elastic depending on where the rolls go.

The divisions, at 140 BPM

One beat at 140 BPM lasts about 429 milliseconds. Every trap hat pattern is some mix of these slices of it:

The Beat Maker counts a bar as 16 steps: beats 1 to 4 sit on steps 1, 5, 9 and 13, and the "ands" on steps 3, 7, 11 and 15. The patterns below assume the clap on step 9 and the kick on steps 1 and 11.

Six trap hi hat patterns

1. Straight 8ths

Hats on the odd steps, 1 to 15. Velocity around 100 on the beats and 70 to 80 on the "ands". This is the floor under a verse, and it leaves room for a busy flow.

2. The gallop

Hits on the beat, the "and" and the "a" of every beat: steps 1, 3, 4, 5, 7, 8, 9, 11, 12, 13, 15 and 16. Velocities 100, 70, 85 in each group. The pair of 16ths at the end of each beat tips it forward into the next one.

3. Sixteenths with a hole

Hats on all 16 steps except step 9, where the clap lands alone. Accent the 8th-note steps at about 100 and drop the in-between 16ths to 55 to 65. The gap under the clap makes the backbeat crack harder than any EQ move.

4. The triplet turn

Straight 8ths for three beats, then six 16th-note triplets across beat 4, steps 13 to 16. Start the six at 60 and finish at 105. Put it on bar 2 of every four and the loop gets a lift halfway round.

5. The 32nd roll

Straight 8ths for three beats of bar 4, then eight 32nd notes across beat 4, climbing from 50 to 110 and landing on the kick at step 1 of the next bar. It's the biggest roll you have, so save it for the bar before a hook.

6. The open-hat answer

Straight 8ths, but the closed hat on step 15 of every second bar becomes an open hat at about 90. On the Electronic kit, alternate Hihat and Pedal Hihat inside a roll for a two-tone flicker.

Why rolls work

A roll is a fill shrunk to one beat. The hits get closer together as they approach the downbeat, so the ear leans forward and the next kick lands with more weight. Triplets add a second pull: three against the grid's four, the tension trap borrows from swing without swinging anything.

Velocity is the other half. The same eight 32nds at one flat level buzz like a stuck note; climbing from soft to loud, they read as a gesture. And rolls only mean something against plain bars. If every bar rolls, none of them do.

Program them in Veena

Ask CoProducer for the whole hat part. Paste the prompt at the bottom of this page. CoProducer has dedicated trap guidance and knows what "triplet rolls and velocity stutter" means. It offers three takes in one carousel: hover a card to hear it, press Enter to add. Rolls go into the MIDI at their own division, triplets and 32nds included, not squeezed onto the nearest 16th.

Swap to a trap kit. New CoProducer drums land on the Pop kit. Say "swap the drums to the Electronic kit" for tight, synthetic hats, or pick Electronic or TR909 from the preset menu on the left of the Beat Maker.

Edit on the grid. Double-click the clip and it opens in the Beat Maker. Drag along the Hihat row to paint 8ths or 16ths; click a step to remove one. Hover any hit and drag its velocity bar, from 1 to 127; new hits start at 100. Add brings in Pedal Hihat, and Hihat Open is always there.

Draw rolls by hand. Load your own hat one-shot onto Veena's 16-pad sampler. Its grid snaps to 1/3 Beat, 1/6 Beat and 1/8 Beat, so 8th-note triplets, 16th-note triplets and 32nds are a click away.

Change them in words. "Take the rolls out of the verse", "make the bar 8 roll a triplet", "softer hats in the intro". Each change is one Ctrl or Cmd+Z away from undone.

Common hi-hat mistakes

Rolls in every bar. Every hat at velocity 100. A hat sitting right on top of the clap. The same roll copied into every phrase. And an open hat so loud it swallows the kick after it. Fix one at a time and loop four bars between each.

The full kit, kick and clap included, is written out in the trap drum pattern grids. Drill takes the same hats into a 3+3+2 skip; see the drill drum pattern. To build the whole beat around them, go to make trap beats, or start clicking in the free online beat maker. The AI drum generator turns a one-line description into a drum part in any style.
