Basic noise source. Three independent audio outputs — WHITE (full-spectrum), PINK (1/f, -3 dB/oct via Voss-McCartney), BROWN (leaky-integrated white: flat below a ~77 Hz corner at 48 kHz, -6 dB/oct above it). All outputs share a single LEVEL knob, which is one multiplier and not one loudness — brown leaves 7.1 dB and pink 12.3 dB below white. No CV inputs.

A pure noise source with three independent spectral flavors on three separate outputs: white (flat), pink (1/f, -3 dB/oct) and brown (leaky-integrated white). Each flavor is a 2-second table generated ONCE when the module spawns and looped forever after, so the colour is baked into the table — there is no filter and no morph, and every jack is live the instant the module appears. Mental model: patch any combination into different channels to layer timbres — white for brightness, pink for warmth, brown for rumble. TWO THINGS WORTH KNOWING BEFORE YOU MIX. First, the taps are NOT level-matched: one LEVEL knob drives all three, but brown leaves 7.1 dB and pink 12.3 dB below white, so equal channel gains do not give equal loudness. Second, brown is a one-pole low-pass rather than a pure slope — it is flat below about 77 Hz (at a 48 kHz interface; the corner scales with the sample rate) and only -6 dB/oct above that, which is why it reads as rumble rather than as a tilt.

outputs

id	cable	what it does
`white`	audio	Full-spectrum white noise with flat frequency response; uniform random amplitude across all audible frequencies. The loudest of the three taps by a wide margin (-4.77 dBFS at LEVEL 1) and the tap the lane meter reads, since it is the first audio output declared. One of three independent outputs sharing the LEVEL control. audio signal
`pink`	audio	1/f pink noise at -3 dB per octave slope; warmer than white noise with attenuated highs. Useful for smooth, natural-sounding textures. The QUIETEST tap — 12.3 dB below white from the same LEVEL setting. One of three independent outputs sharing the LEVEL control. audio signal
`brown`	audio	Leaky-integrated white noise: FLAT below its -3 dB corner (about 77 Hz at 48 kHz, and the corner moves with the interface sample rate) and -6 dB per octave above it, so it is the darkest flavor without being a pure 1/f² tilt. It also has no hard bound — its peak drifts past full scale on most spawns at LEVEL 1, where white and pink cannot. Sits 7.1 dB below white. One of three independent outputs sharing the LEVEL control. audio signal

controls

control	what it does
Level	Master gain applied equally to all three noise outputs, from silence (0) to full amplitude (1). Equally in the sense of one multiplier, NOT one loudness: the three tables have different RMS, so the taps stay 7.1 dB and 12.3 dB apart at every setting. Default 0.5 provides moderate headroom; raise it to push the noise through downstream processing, lower it to blend subtly into a mix. Above about 0.78 the brown tap can peak past full scale.
