Techno Bassline

A techno bassline is short, low and relentless: notes on the 16ths between the kicks, one root for bars at a time, and movement from rhythm rather than melody. Below are four patterns, step by step. Veena, a free AI DAW with a personal music producer built in, writes them for you: CoProducer hears your kick first, then builds the low end around it.

Every note name here is what you draw in Veena's piano roll. The synth basses sound an octave below the drawn note, so F2 in these grids is the 43.7 Hz F that shakes the room.

Four techno bassline patterns, written out

1. The rolling sub · Techno Sub · 130 BPM · F minor

16ths      1   e   &   a   2   e   &   a   3   e   &   a   4   e   &   a
Kick       X   .   .   .   X   .   .   .   X   .   .   .   X   .   .   .
Bars 1–3   .   .   F2  F2  .   .   F2  F2  .   .   F2  F2  .   .   F2  F2
Bar 4      .   .   F2  F2  .   .   F2  F2  .   .   Ab2 Ab2 .   .   Eb2 Eb2

Two 16ths after every kick, on the "and" and the "a". The kick owns the beat, the sub fills the tail, and the pair becomes one rolling engine. Bar 4 moves to Ab and Eb for two beats, just enough to reset the ear before the loop comes round.

2. The polymeter · Pluck Bass · 128 BPM · F minor

16ths   1   e   &   a   2   e   &   a   3   e   &   a   4   e   &   a
Bar 1   F3  .   C4  F3  .   C4  F3  .   C4  F3  .   C4  F3  .   C4  F3
Bar 2   .   C4  F3  .   C4  F3  .   C4  F3  .   C4  F3  .   C4  F3  .
Bar 3   C4  F3  .   C4  F3  .   C4  F3  .   C4  F3  .   C4  F3  .   C4

One three-step cell, F, rest, C, repeated against a four-beat bar. It lands in a different place every bar and only realigns every three bars, so the loop never quite settles. That drift is the hypnosis. It sits an octave above the sub, so it can run over pattern 1 without touching the kick.

3. The melodic roller · Dirty Sub · 124 BPM · A minor, over Am, F, C, G

16ths   1   e   &   a   2   e   &   a   3   e   &   a   4   e   &   a
Bar 1   .   A2  A2  A2  .   A2  A2  A2  .   A2  A2  A2  .   A2  A2  A3
Bar 2   .   F2  F2  F2  .   F2  F2  F2  .   F2  F2  F2  .   F2  F2  F3
Bar 3   .   C3  C3  C3  .   C3  C3  C3  .   C3  C3  C3  .   C3  C3  C4
Bar 4   .   G2  G2  G2  .   G2  G2  G2  .   G2  G2  G2  .   G2  G2  G3

Three 16ths after every kick and an octave flick on the last one of each bar: the driving low end under melodic techno. The i–VI–III–VII progression moves the root, so the rhythm can stay identical for 64 bars. Pull the "e" of each beat down in velocity and the line swells into every kick.

4. The acid line · Acid Bass · 132 BPM · E Phrygian

Phrygian puts F a half step above the root E, and that rub is the menace. Step 2 slides up an octave into step 3, step 10 slides from E3 down to D3, step 15 slides up a fifth into B2. Accents are just higher velocity: Veena's Acid Bass opens its filter wider on harder notes.

Why techno bass works this way

The kick owns the beat. Kick and sub both live under 100 Hz, and two lows on the same 16th smear into one. The rolling sub and the melodic roller never touch steps 1, 5, 9 and 13. The polymeter and the acid line can cross them because their bite lives higher up, in the octave jumps and the filter.

Rhythm moves, pitch stays. Techno changes a root every four, eight or sixteen bars. The groove, the filter and the arrangement carry the change instead.

Short notes, no stacking. Techno Sub settles onto a lower sustain level within 180 ms of each hit, before the next kick arrives. Pluck Bass is gone in about 160 ms. The low end breathes between hits.

Build a techno bassline with CoProducer

Open daw.veena.studio, sign in with Google, and paste:

Make a 130 BPM peak-time techno track in F minor: TR909 kit with a four-on-the-floor kick, open hats on the offbeats and straight 16th closed hats; a Techno Sub bassline rolling on the last two 16ths of every beat on F, moving to Ab and Eb on beats 3 and 4 of every fourth bar; a Pluck Bass riff an octave above that repeats a three-step F, rest, C cell against the four-beat bar; a Dark Pad held underneath. 16 bars of kick and sub, 16 with the riff, an 8-bar break with the kick out, then a 32-bar drop.

CoProducer writes the kick first, reads where its notes actually landed, then writes both bass parts into the gaps. Each part arrives as 3 options: browse with the arrow keys, hear each against the kick, press Enter on the one you keep. In Veena's own data, techno has the highest day-one success of any genre: 91.7% of new users who ask for it get a finished first result on day one.

Tweak it in the piano roll

Double-click a bass clip to open its piano roll. Set snap to 1/4 Beat for 16ths. Select a bar and press Ctrl or Cmd with an arrow key to throw it up an octave for a build. Every bass here sits on Veena's own synth, with four knobs on each clip:

• Techno Sub: MOVEMENT adds glide, but only between notes you overlap. BODY sets how much weight stays clean below the drive.
• Acid Bass: BRIGHTNESS is the cutoff, MOVEMENT the length of the squelch, BODY the drive, EDGE the resonance.
• Knobs live on the clip: copy the acid clip every 8 bars and turn BRIGHTNESS up a notch on each, and the filter opens from a murmur to a scream across 32 bars.

Or just say it: "make the sub roll on all three 16ths in the drop", "mute the bass for the last bar before the break". One undo reverses any change.

Mistakes that flatten a techno low end

1. Bass on the kick. Move it to the 16ths after.
2. Too many notes. If the bassline could be sung, it is probably a melody.
3. Drawn too low. An F1 on a synth bass sounds at 21.8 Hz, below what a club system can reproduce. Draw it in octave 2.
4. An untuned kick. A kick at 50 Hz under an F at 43.7 Hz beats against it. Tune one to the other.

The drums under these lines are in techno drum patterns, the whole track is on how to make techno, and the four-on-the-floor cousins live in house bassline grooves. The bassline generator writes new lines against your kick, and when a part needs chords, the chord progression generator writes them first.
