Logic Pro Step Sequencer Tutorial: Drums and Patterns

What is the Step Sequencer in Logic Pro?

The Step Sequencer is a Logic Pro editor that builds repeating drum, bass and melodic patterns on a grid of steps, the way a classic drum machine does. Apple added it in Logic Pro X 10.5 in May 2020 as part of a batch of beat-making tools^[1].

Every pattern lives in a pattern region in the Tracks area or a pattern cell in the Live Loops grid. Each region acts as its own independent sequencer with its own pattern, settings and view options, so a project can hold as many different patterns as you need^[2].

The grid has two row types. Note rows fire MIDI notes on every active step, and automation rows write stepped automation for any automatable parameter, including plug-in controls and Smart Controls^[2].

Step Sequencer vs Piano Roll

The Piano Roll is better for long melodic parts and anything played in from a keyboard. The Step Sequencer is faster for loops of one to four bars where you want per-step control over velocity, repeats and probability.

How do you create a pattern region in Logic Pro?

Control-click an empty area of a software instrument track and choose Create Pattern Region. The Step Sequencer opens in the Editors area below the Tracks area, ready for you to click steps on^[3].

1. Load a drum kit
   Create a software instrument track and pick a Drum Machine Designer kit from the Library. With a Drum Machine Designer patch, row headers show kit piece names such as Kick or Snare instead of MIDI note numbers.^[7]
2. Create the region
   Control-click in the empty track lane and choose Create Pattern Region. You can also select an empty MIDI region, open the Step Sequencer from the Editors area and click a step.^[3]
3. Start from a preset or a blank grid
   Click the Pattern Browser button in the Step Sequencer menu bar to load a premade pattern, or choose Functions > Clear Pattern to start empty.^[4]
4. Preview while the project is stopped
   Click the Preview button to loop the pattern on its own. Press Space to hear it against the rest of the song.^[3][4]
5. Stretch the region
   Drag the right edge of the pattern region to cover 4, 8 or 16 bars. The region length decides how many times the pattern repeats in the song.^[4]

Rows, steps and edit modes explained

Each step has several values stacked on top of it, and the Edit Mode selector decides which one you are drawing. Step On/Off is always on the left button; every other mode lives in the pop-up menu on the right, and the chosen mode applies to all rows at once^[5].

To see several modes for one row at the same time, click the disclosure arrow in the row header to open subrows. Each subrow shows a different edit mode, which is the fastest way to shape velocity and note repeat on a hi-hat row without switching modes back and forth^[5].

The Step inspector adds finer controls that are not in the grid. For Note Repeat you get Velocity Ramp (negative values fade, positive values swell), Velocity Curve and Distribution, which squeezes the repeats toward the end or the start for an accelerando or decelerando feel^[7]. Distribution is the tool for trap-style hat rolls that speed up into the snare.

How do pattern length and step rate work?

Pattern length sets how many steps each row can hold, and step rate sets how long each step lasts as a note value. A 16-step pattern at /16 is one bar of 4/4; the same 16 steps at /8 last two bars^[6].

The Pattern Length menu is split into 4-, 3-, 5- and 7-based sections for 4/4, 3/4, 5/4 and 7/8. When you lengthen a pattern, the new steps copy the existing ones, so you only have to edit the variations. Past 16 beats the grid splits into pages that you switch with the overviews above the grid^[6].

Polymeter with Loop Start and Loop End

Each row can loop on its own. Shorten a shaker row to 3 or 5 steps inside a 16-step pattern and it drifts against the kick. Apple notes that rows that do not divide evenly make the overall pattern longer, because it only repeats when every row lines up again^[6]. Ping-Pong playback doubles the length, and Random playback makes it effectively endless^[6].

How to program a hip-hop drum pattern step by step

Start with a one-bar, 16-step pattern at /16 and around 140 BPM, then add variation with Chance, Note Repeat and step conditions rather than by copying bars by hand. The numbers below are starting points to tweak by ear, not rules.

1. Place the anchors
   Put the kick on step 1 and a second kick somewhere between steps 8 and 11. Put the snare or clap on step 9 for a half-time feel, or on steps 5 and 13 for a straight backbeat.
2. Lay the hats
   Turn on every other step (1, 3, 5 and so on) on a closed hat row. Set Velocity between about 70 and 110 so the offbeats sit lower than the downbeats.
3. Add rolls with Note Repeat
   Pick two or three hat steps before the snare and set Note Repeat to 2, 3 or 4. Add a negative Velocity Ramp for a roll that fades, or use Distribution for a roll that speeds up.^[7]
4. Introduce variation with Chance
   Drop ghost kicks or percussion hits in at 30 to 60 percent Chance. Apple notes that longer regions give more variety because Chance applies on each repeat of the pattern.^[4]
5. Mark the first and last loop
   In the Step inspector, set a crash step's Condition to First Loop and a tom fill to Last Loop. Apple suggests exactly this use: a cymbal at the start of a region and a tom at the end.^[7]
6. Add swing
   In the Pattern inspector, raise Swing and apply it to 16th notes. Try 55 to 60 percent first; higher values quickly sound drunk.^[7]

For deeper hat programming, including roll lengths and hat choices, see how to program trap hi-hats in Logic Pro. If your grid sounds stiff after all this, the ideas in quantizing drums without killing the groove apply here too: small Offset moves on single steps often fix more than global swing.

Using Drum Machine Designer kits and your own samples

Drum Machine Designer is the kit instrument that the Step Sequencer understands best. When a pattern uses a Drum Machine Designer patch, the Row Assignment menu lists kit pieces by name, so changing the snare row to a clap is a single menu choice^[7].

Since Logic Pro 10.5, each Drum Machine Designer pad can host Quick Sampler or Drum Synth^[1]. That means you can drag your own one-shots onto pads and program them in the same grid. A folder of free drum kits with clearly named kicks, snares and hats makes this much faster. For chopping loops onto pads, the sibling guide on the Logic Pro Quick Sampler covers Slice mode.

• Add a row Use the Add Row pop-up above the row headers and pick a kit piece, a fixed note, a Melodic row or an automation parameter.^[3]
• Learn mode Choose Learn from the Add Row menu, then hit pads on your controller to create rows for each sound you play.^[3]
• Automation rows Add an automation row for a filter cutoff or send level and draw stepped moves. Set the row's Automation Mode to Slide for smooth changes or Latch to hold each value.^[7]

How to convert a pattern region to MIDI and back

Control-click the pattern region and choose Convert > Convert to MIDI Region. The result is a normal MIDI region you can edit in the Piano Roll, quantize or send to another project^[8].

The reverse also works: Control-click a MIDI region and choose Convert > Convert to Pattern Region. Logic rebuilds note positions with Offset values and note lengths with Tie and Gate. A converted pattern can hold at most 64 steps, so Apple recommends source regions no longer than 4 bars of 4/4 with events no closer than a 1/16 note^[8].

Common Step Sequencer mistakes and quick fixes

• Pattern cuts off early The region is shorter than the pattern. Drag the region end out until it covers every page.^[6]
• Chance never changes The on or off result for a Chance step is fixed when you edit the value and stays that way until you edit it again, so re-drag the value to reroll.^[5]
• Loop feels longer than intended Rows with uneven Loop End values do not line up until they all restart together. Use 4, 8 or 16 step rows if you want a clean one-bar loop.^[6]

Once the drums work, the next job is arrangement. Build intro, verse and hook variants as separate pattern regions and follow a plan such as the one in beat structure and song arrangement.
