How to Make Downtempo Trip-Hop Like Portishead & Massive Attack in Logic Pro

In this 40-minute live session, producer Mikas slows things down to 100 BPM to build a smooth, moody downtempo trip-hop track from scratch — the dark, deep, break-beat-driven sound made famous by Massive Attack and Portishead. Working entirely in Logic Pro with no edits and no cuts, he layers sampled loops, records electric piano and bass by hand, and stacks synths and pads until the foundation of a full track takes shape.

What you’ll learn

• Choosing and layering break-beat loops to build a downtempo foundation
• Sculpting loops with EQ resonance and automating a filter cutoff sweep
• Recording electric piano keys, then quantising and editing velocity for a human feel
• Programming a chunky low-end bassline and an ARP-style bass alternative
• Adding live-played percussion, hi-hats, and tempo-synced delay
• Texturing the mix with a grungy pad, an angelic contrast pad, and a dreamy piano lead

1. Browse and layer the foundation loops

Mikas starts in Logic Pro’s loop browser, auditioning break beats until he finds a cut-up beat he likes. Dropping it into the project, Logic automatically time-stretches the loop to match the 100 BPM tempo. Rather than leaving it bare, he layers a second loop on top so two rhythmic elements play together — keeping the break beat while bringing in a more tribal, tom-like feel to add variation.

2. Sculpt the loop with EQ and a filter automation

Instead of reaching for a dedicated filter, Mikas EQs the loop himself: he sets the Q and pushes the resonance to emphasise a frequency band. He then creates an automation lane in Touch mode and draws a cutoff-frequency move so the filter opens and closes through the beat. When the first pass cuts too abruptly and produces a harsh squeak, he adds an extra automation point to smooth the transition over a longer span.

3. Record electric piano keys

With the rhythm in place, Mikas plays in an electric piano part for that classic Massive Attack key feel, adding reverb to give it air and dimension using his own go-to bus reverb preset. After recording, he quantises the MIDI to lock the notes to the grid, trims note lengths, removes a couple of unwanted hits, and then edits the velocity lane — pulling down notes that are over the top so the part keeps its dynamics rather than sounding flat.

4. Build a chunky rolling bassline

Next he chases the “vision” of a big, chunky rolling bass sitting behind the keys. He auditions sounds, plays a single root note, then works out a simple progression with one key change. To make the bass sit in the mix he adds a little low end, then filters out the very lowest frequencies — a trick that can give the bass more perceived power by focusing energy on the frequency you actually want to trigger.

5. Add synth texture and an ARP bass alternative

To bring in movement, Mikas drops in a synth texture that drifts in and out behind the beat. Not fully sold on the original bass, he tries a groovier, more electronic ARP-style bass instead, layering two synth parts and lowering both volumes so they blend rather than fight. A crescendo keeps the part rising through the phrase.

6. Layer live percussion and tempo-synced hats

Mikas opens a drum kit and plays percussion in live alongside the keys. He experiments with a delay on a percussive element, switching from an unsuitable longer delay to a simple 16th-note delay locked to the tempo. Then he stacks a second set of hi-hats in his own more electronic style, reaching for an open 808/909-type hat to sharpen the groove around his recurring four-beat drop.

7. Stack a grungy pad and an angelic contrast pad

For texture and edge he builds a simple chord on a grungy pad, extends the region, and rolls off the low end so it sits cleanly under the mix. He then adds a softer, dreamy “angelic” pad — a vocal-like voice sound — as a contrast layer to balance the grit, again dropping the lows so the pads don’t muddy the low end.

8. Record a dreamy piano lead to finish

To top the arrangement, Mikas plays in a melodic lead, choosing keys over a lead sound for this style. He tames an over-bright, over-velocity take by easing back the velocity and considering dropping it an octave while opening the filter a touch. With the lead in place, every core element — beats, keys, bass, synths, pads, and lead — is recorded and ready to be expanded into a finished track.
