To make a pluck sound, take a bright oscillator and give it a fast attack with a short decay on both the amp and filter envelopes, so the note snaps in and fades quickly like a string being plucked. Add a touch of reverb or delay for space and you have a tight, percussive synth that works in everything from house to pop to ambient.
This works in any synth — Serum, Vital (free), Massive X, Arturia Pigments or Ableton’s Wavetable. The key to a pluck is all in the envelopes.
To make a pluck sound, pick a bright oscillator
Plucks need transient detail, so start with a harmonically rich waveform — a sawtooth or a bright wavetable position. A square wave gives a hollower, more retro pluck. A single oscillator keeps things clean and snappy; add a second detuned voice if you want a little width and thickness. New to oscillators? Our guide on how to design sounds with a synth covers the basics.
Shape the envelopes for the snap
This is the heart of a pluck. On the amp envelope, set a near-instant attack, a short-to-medium decay, zero or very low sustain, and a short release. With sustain at zero, the note rings out and dies even while the key is held — exactly like a plucked string.
Then route a second envelope to filter cutoff with the same fast attack and short decay. Start the filter open at the attack and let it close as the note decays. That downward filter sweep on every note is what gives a pluck its characteristic “ptew” snap. Adjust the decay time to taste — shorter for tight stabs, longer for a more sustained pluck. For more envelope technique, see our essential sound design techniques.
Set the filter and resonance
Use a low-pass filter so the filter envelope has something to sweep. Add a moderate amount of resonance to emphasise the cutoff frequency as it moves — this adds the zappy, vocal quality plucks are known for. Too much resonance and it whistles, so dial it back if it gets piercing.
Add subtle modulation
Plucks are short, so heavy modulation is wasted, but small touches help. Velocity-to-filter-cutoff makes harder-hit notes brighter, adding playability and dynamics. A tiny pitch envelope (a fast downward blip at the start) adds attack and percussive bite. For routing ideas, read how to use modulation for sound design.
Process for space and groove
Because plucks have lots of silence between hits, effects fill that space:
- Delay: a tempo-synced delay (dotted eighth is a favourite) turns a simple pluck pattern into a rolling, rhythmic hook.
- Reverb: a short-to-medium reverb gives the pluck a tail and depth. See how to use reverb for sound design.
- EQ: high-pass to remove low rumble and keep the pluck crisp.
- Saturation: a little drive thickens the body.
For huge plucks, layer two — one bright and one with more low body — and combine them. Our guide on how to layer sounds explains the workflow.
Frequently asked questions
Why does my pluck sound dull?
Either the oscillator lacks harmonics or the filter is closed too far at the attack. Open the filter cutoff, make sure the filter envelope opens brightly on the attack, and choose a richer waveform like a saw.
How do I make a pluck more percussive?
Shorten the amp decay, drop the sustain to zero, add a fast pitch-down envelope at the start, and increase velocity sensitivity so transients pop. A touch of saturation adds extra attack.
What is the difference between a pluck and a stab?
They overlap. A pluck is usually a single-note, fast-decaying sound with a filter snap, while a stab is often a chord hit with a similar short envelope. Both rely on fast attack and short decay — a stab just plays multiple notes at once.
