Noise — The Odd Friend
All frequencies at once. Useful, surprisingly often.
All frequencies at once. The secret of every hi-hat.

// WHAT IT DOES
Noise is a special signal that contains every frequency at roughly the same level. Because no single pitch dominates, you don't hear a 'note' — you hear a hiss.
It's the raw material of any sound that isn't pitched: hi-hats, claps, snare bodies, breath, wind, ocean. Shape it with a filter and an and almost any percussive sound is possible.
Mixed quietly under a synth pad it adds 'air' — the impression of breath that makes analogue synths feel alive.
Think of it like → Noise is the synth equivalent of a snare's wires — buzz with no pitch, ready to be shaped.
▸ WHY YOU CARE
- • Most drum machines build their unpitched percussion from a noise oscillator.
- • A pinch of noise behind any pad or vocal makes it sit in the mix more believably.
- • It's the cheapest way to add movement to a static sound.
// SEE & HEAR IT
▸ Two oscillators blend to one waveform. Detune fattens by making them slightly out of tune.
▸ HOW IT WORKS
▸ Signal flow — watch the dot
▸ SIGNAL FLOW
Glowing dot = your signal travelling through Live.
▸ LISTEN FOR
- • Noise has no pitch — bending the synth pitch barely changes it.
- • Filter sweeps colour the noise without giving it a note.
- • Short envelopes turn noise into hats; long envelopes turn it into wind.
▸ WALKTHROUGH (4 steps)
- 1. DO: Switch the oscillator to noise. Play a key.▸ LISTEN: A hiss. No pitch.
- 2. DO: Drop a filter and close it.▸ LISTEN: Hiss becomes a 'shhh' — pink-ish.
- 3. DO: Set a snap-fast amp envelope (1 ms , 50 ms decay, 0 ).▸ LISTEN: Closed hi-hat.
- 4. DO: Lengthen decay to 300 ms.▸ LISTEN: Open hi-hat.
▸ COMMON MISTAKES
- ✗ Adding too much noise to a pad — air becomes hiss quickly.
- ✗ Trying to play 'noise melodies' (you can't — no pitch).
