Rhythm & Groove.

A drum step sequencer for learning groove: program kicks, snares and hats, switch between 4/4, 3/4, 6/8 and odd meters, add swing, and load the classic patterns behind boom bap, trap, house and dembow. Export to Ableton as MIDI.

Beat — grid

Program a drum groove on a step grid, change the time signature and swing, and hear every change instantly. Export it to Ableton as MIDI when it slaps.

Time & feel

What makes a beat feel the way it does — meter, swing, syncopation, accents and half-time. Every card has a button that loads an example into the grid.

Time signatures

The top number is beats per bar, the bottom is the note that gets the beat. 4/4 = four quarter notes (almost all pop, hip-hop and EDM). 3/4 = three (waltz). 6/8 = six 8th notes felt as two big beats of three. Odd meters like 7/8 group 2 + 2 + 3.

Swing

Swing delays every second 16th note, so pairs of notes become long-short. A little (10–20%) adds bounce; a lot (30%+) feels lazy and laid-back. It's the MPC sound of boom bap and lo-fi.

Syncopation

Accents between the beats instead of on them. A kick that lands just before a beat, a snare on the "a" — the ear expects the beat and gets surprised. Dembow is syncopation on repeat.

Accents & ghost notes

Not every hit is the same volume. Accents push the main beats; quiet ghost notes fill the gaps without cluttering. A hat pattern with accents on the beats instantly sounds more human.

Half-time

Put the snare on beat 3 only and the groove feels half as fast as the tempo. That's how trap sits at 140 BPM yet feels like 70 — heavy, with room for fast hats on top.

The theory behind it

Note values, meters and groove are covered step by step in the Music Theory course.

03

Genre grooves

The skeleton of each genre's drums. Load one, then make it yours — most great beats start from a classic pattern and change one thing.

86–95 BPM · swung 16ths

Boom bap

Kick on 1 and the "and" of 3, snare on 2 and 4, swung hats. The head-nod of 90s hip-hop — swing is what makes it bounce.

130–150 BPM · half-time

Trap

A single snare/clap on beat 3 makes 140 feel like 70. Busy 16th hats with a roll at the end, 808 following the kick.

120–128 BPM · four on the floor

House

Kick on every beat, clap on 2 and 4, open hat on every off-beat — the off-beat hat is the whole "lift".

88–100 BPM

Reggaeton (dembow)

Kick on every beat with the snare on the "a" of 1 and the "and" of 2 — the 3-3-2 pattern that defines the genre.

70–85 BPM · heavy swing

Lo-fi

Lazy, heavily swung, soft hats and a sparse kick. Leave space — the dust and the chords do the rest.

100–130 BPM

Rock

Straight 8th hats, backbeat snare on 2 and 4, kick on 1 and around 3. No swing — it drives.

140–175 BPM

Half-time

Snare on beat 3 only, kick wherever it pushes. Used across trap, dubstep and drum & bass to feel heavy at high tempos.

90–180 BPM

Waltz 3/4

Three beats per bar: a strong ONE then two lighter beats. OOM-pah-pah.

≈ 60–80 dotted-quarter

6/8 groove

Two big beats per bar, each split into three — the rolling, swaying feel of R&B ballads and blues.

04

Into Ableton

From this grid to a Drum Rack in four steps.

1

Export the groove

Build a pattern here and press Export MIDI. You get a 4-bar .mid file with two tracks: Drums (General MIDI drum notes) and 808, at your tempo and time signature.

2

Drop it on a Drum Rack

Create a MIDI track with a Drum Rack (any 808 or 909 kit) and drag the file in. The pads line up with the standard map: C1 kick, D1 snare, D#1 clap, F#1 closed hat, A#1 open hat, C#1 rim, A1 tom.

3

Put the 808 on its own track

Ableton splits multi-track MIDI files into separate tracks — give the 808 track an 808 sample in Simpler (or Operator) and turn on Glide if you want slides.

4

Swing it in Ableton instead

Prefer to swing inside Ableton? Export with swing at 0%, then drag a groove from the Groove Pool (the MPC swing grooves are a classic) onto the clip and adjust its amount.
