Player Panels

The seven panels of the Player — grid, pads, mixer, effects, and more

The Player is k2k’s live performance engine. Load sounds from the Editor into memory slots, trigger them from pads, sequence them on a step grid, shape them with effects — all in real time.

Panels

The Player screen is built from seven interlocking panels. Each one handles a different job.


Grid Panel

What it does The step sequencer where you build rhythmic patterns across eight tracks.

When you’d use it Open whenever you’re composing beats, programming sequences, or automating parameters over time. It’s the central workspace of the Player.

Quick tour

  • Each row is a track. Click cells to toggle steps on or off. Active steps light up with brightness proportional to velocity.
  • A colored playhead sweeps across the grid during playback, and cells flash as they fire.
  • Above the grid, the automation bar lets you select which parameter to paint into steps: Velocity, Pitch Shift, Time-Stretch, Decay, Pan, Probability, Subdivision, Conditioning, or any of the eight effect sends (A1-A8). Select a parameter, then drag up or down on cells to set per-step values.
  • Each track has page navigation arrows and a page-group mode selector (Loop, Increment, or Random) for patterns longer than one page.
  • To the left of each row: a pad-assignment button (colored to match the assigned pad), a play/stop toggle, a launch-quantize selector, a clock-divider display, and the current page number.

Pads Panel

What it does A 4x4 grid of sixteen trigger pads, each linked to a memory slot.

When you’d use it Tap pads to audition sounds, assign sounds to tracks, or fire one-shot hits during a live session.

Quick tour

  • Pads are arranged in a four-by-four matrix, numbered 1-16.
  • Each pad shows the color of its assigned slot. Empty pads appear dim.
  • Click a pad to trigger its sound immediately. Pads flash on trigger.
  • Right-click a pad to open its settings in the Parameter Panel (slot assignment, label, tuning, envelope, filter).
  • Velocity responds to how the pad is struck when using a MIDI controller.

Mixer Panel

What it does Eight track strips plus a master strip for balancing levels and positioning sounds in stereo.

When you’d use it Use the Mixer to set relative volumes, pan instruments left or right, isolate tracks with Solo, or silence them with Mute. The master strip sets the final output level.

Quick tour

  • Eight vertical channel strips sit side by side, one per track, with a wider Master strip on the right.
  • Each strip has Solo and Mute buttons at the top, a Pan knob in the middle, and a Volume knob below.
  • The Master strip has a vertical VU meter and a gain control with a peak-dB readout.

FX Slots Panel

What it does A chain of eight serial effect slots (A1 through A8) for the selected track.

When you’d use it Open the FX panel to add, swap, or tweak effects on any track. Each track has its own independent chain, so you can give the kick a compressor while the hi-hat gets a phaser.

Quick tour

  • Slots are laid out in a 2x4 grid: A1-A4 on top, A5-A8 below, with signal flowing left to right, top row then bottom row.
  • Click a slot to select it. A dropdown lets you pick the effect type; a toggle enables or disables the slot.
  • The selected slot’s full parameter set appears in a side area within the panel.
  • Copy and paste slot configurations between positions. A global Bypass button disables the entire chain at once.

Available effect types (27)

Reverb: Reverb, Native Reverb, Shimmer Reverb, Spring Reverb Delay: Delay, Matrix Delay, Multi-Tap Delay, Mod Delay Distortion: Distortion, Saturator, Soft Clipper, Wavefolder, Harmonic Shaper, Bitcrush Dynamics: Compressor, Expander, Gate, Limiter Filter: Filter, Multimode Filter, Parametric EQ, Comb Resonator Modulation: Phaser, Leslie, Frequency Shifter Pitch: Pitch Shift Spatial: Spatial Lab

See the individual effect entries in the Lexique for parameter details.


Slot Bank Panel

What it does A browsable table of 128 memory slots that hold audio ready for the pads and tracks.

When you’d use it Go here to import new sounds, preview what’s loaded, rename slots, export audio, or clear slots you no longer need.

Quick tour

  • A sortable table lists each slot’s number, name, duration, and type (Graph or External).
  • A filter bar at the top lets you show All slots, only Assigned ones, only Loaded ones, or only Empty ones. A text search narrows results further.
  • Press and hold the preview button on any row to audition the slot’s audio.
  • Right-click a slot to open a context menu: Play Preview, Rename, Clear Slot, Export as WAV, Export as FLAC, or Reveal in Folder.
  • The Import Audio button opens a file browser to load WAV or FLAC files into empty slots. Import Folder loads an entire directory at once.

Scopes Panel

What it does Real-time audio visualizations that follow the Player’s live output.

When you’d use it Keep the Scopes open for visual feedback while performing or mixing — watch transients hit, confirm frequency balance, or spot artifacts.

Quick tour

  • A tab bar switches between three views: Waveform, Spectrum, and Spectrogram.
  • Each scope updates in real time from the audio output, fed through a lock-free buffer so it never interrupts playback.
  • Scope-specific settings (scale, range, color) are accessible within each tab.

For full details on each scope type, see Player Scopes.


Parameter Panel

What it does A context-sensitive editor that shows different controls depending on what you’ve selected in the Player.

When you’d use it Click a step, pad, or track anywhere in the Player, and the Parameter Panel updates to show that element’s settings. It also hosts the Slot Bank browser as a second tab.

Quick tour

  • Two tabs at the top: Parameters and Slot Bank. The Parameters tab is context-driven; the Slot Bank tab shows the Slot Bank Panel inline.
  • Step view (click a step in the Grid): velocity, pitch shift, time-stretch, decay, pan, probability, conditioning, start offset, subdivision editor, per-step filter, per-step ADSR envelope, and per-step effect sends.
  • Pad view (click or right-click a pad): slot assignment, pad label, slot trimmer, time-stretch, pitch, filter, and ADSR envelope.
  • Track view (click a track header): track length, clock divider, page-group mode, swing and groove settings, sync options, and Euclidean pattern generator.
  • When nothing is selected, the panel shows a prompt to select something.
