k2k audio k2k Lexique
Every node, scope, and color mode in k2k — what it does, when to reach for it, and how to use it.
Editor — Nodes
The Editor is where you dissect and transform audio. Build processing chains with a visual node graph — 130 nodes across 19 categories. Each node is a building block: load audio, extract layers, filter, distort, morph, sequence, and recombine.
- Audio I/O
Audio input and output — loading files into k2k - Slicing
Cut, rearrange, and assign audio to playback slots - Masks
Frequency, amplitude, and time region selectors - Extractors
Separate audio into layers — transients, harmonics, noise, formants - Filter
Shape the frequency spectrum — EQ, resonators, adaptive filters - Dynamics
Compressors, gates, limiters, and transient shapers - Distortion
Saturation, clipping, bit crushing, and wavefolding - Delay
Echoes, multi-tap delays, and matrix routing - Reverb
Room simulation — plates, convolution, shimmer, springs - Modulation
Chorus, phaser, frequency shifting, Leslie, spectral modulation - Pitch
Pitch shifting and harmonizer - Time
Time stretching, granular, freeze, stutter, and spectral smear - Texture
Surface treatment — smooth, sharpen, saturate, erode - Crossmorph
Blend and morph two sounds together - Phase
Phase correction and creative phase manipulation - Spatial
Panning, width, and spatial mixing - Neural
AI-powered source separation and resynthesis - Utility
Gain, mixing, envelope following, trimming - Subgraph
Encapsulate node groups as reusable blocks
Scopes & Color Modes
Four scopes show your audio from different angles — waveform, spectrum, spectrogram, 3D terrain. Color modes re-paint the same data to reveal amplitude, pitch, transients, phase damage, or harmonic structure. Like switching between X-ray, infrared, and visible light.
- Editor Scopes
Four visual scopes for the Editor — waveform, spectrum, spectrogram, 3D terrain - Player Scopes
Real-time scopes for the Player — waveform and spectrum - Instant Color Modes
Instant color modes — amplitude, harmonics, transients, and more - Deep Analysis Color Modes
Deep analysis color modes — formants, noisiness, spectral features - Color Modes: Phase Observatory
Phase color modes — phase behavior, coherence, and relationships
Player
The Player is k2k's live performance engine. Sounds processed in the Editor flow into a bank of 128 memory slots. Trigger them from pads, sequence them on an 8-track polyrhythmic grid, shape them with effects — all in real time.
Modulation System
Every knob in k2k can come alive. Sweep parameters with LFOs, draw custom curves, or let another signal drive them via sidechain. Right-click any modulatable knob to add movement.
