How do I get the pumping future bass sound?

Sidechain a compressor on the chord bus to the kick with a fast attack, a 3:1 to 4:1 ratio, and a release timed to the beat so the chord ducks and swells back.

Can I make future bass chords with free plugins?

Yes. Vital gives you the supersaw for free and your DAW's stock compressor does the sidechain. The width, the voicing and the pump matter more than the plugin.

Q: Why do my future bass chords sound thin?

Almost always one of three things: plain triads instead of extended chords, a supersaw that is not wide enough, or no sidechain pump. Extend the chords, widen with voices and spread, and duck them to the kick.

Design a future bass supersaw chord progression live — pick a key and four chords, stack detuned voices into a wide wall, shape the filter and swell, and push the sidechain until the chords breathe with the kick. Then copy your exact settings into the recipe and rebuild it in Serum, Vital or your DAW.

01 · KEY

Pick a key and a 4-chord progression, then hit Play — it loops.

02 · SHAPE

Dial voices, detune, filter and the sidechain until it breathes.

03 · COPY

Hit “Copy my settings” and rebuild it in Serum, Vital or your DAW.

SourceOne sawtooth oscillator, unison 7 voices. This is the supersaw — the whole timbre.

DetuneModerate — enough to shimmer, not so much it smears. Widen with unison spread and voice count first, heavy detune last.

ChordExtended, not a triad: major-ninth / add9. Root low, the 3rd, 5th, 7th and 9th voiced high and wide across octaves.

FilterLow-pass to tame the harsh top; automate the cutoff up so the chord opens and swells.

SidechainCompressor on the chord bus keyed by the kick (or a ghost kick). Fast attack, ratio 3:1–4:1, release timed to the beat — this is the pump.

SpaceBig hall/plate reverb, sidechained so the tail ducks out of the kick; widen the stereo, then check mono.

GlueGentle OTT / multiband, high-pass below ~150–200 Hz, cut mud at 150 Hz and harshness at 2–3 kHz.

Tempo~140–170 BPM, half-time feel — a starting point, not a rule.

Free route: Vital (supersaw + stock compressor for the sidechain). Paid shortcuts: Serum, Sylenth1. The width, the extended voicing and the pump matter more than the plugin.

Supersaw chord FAQ

Why do my future bass chords sound thin?

Almost always one of three things: you are playing plain triads instead of extended chords, the supersaw is not wide enough, or there is no sidechain pump. Extend the chords, widen with voices and spread, and duck them to the kick.

How much should I detune the supersaw?

Enough to shimmer, not so much it smears into noise. Widen with unison voices and stereo spread first, and reach for heavy detune last.

How do I get the pumping sound?

Sidechain a compressor on the chord bus to the kick, with a fast attack, a 3:1–4:1 ratio, and a release timed to the beat so the chord ducks and swells.

Is the audio a sample?

No — it is a Web Audio synth building the supersaw live in your browser: detuned saw voices summed through a filter and a tempo-synced sidechain gain.
