Orcalot turns ORCA livecoding into a focused desktop studio for generative music, MIDI performance, sound experiments, and audiovisual sketches. Build patterns on the ORCA grid, read MIDI notes and controller changes into your patches, play polyphonic synth channels, shape reactive shader visuals, record ideas, and save the whole session as a portable .orcalot project.

Core Features

Orca Grid Sequencing

Program generative music patterns directly in the livecoding grid with familiar Orca operators and commands.

MIDI Controller Workflow

Read MIDI notes and control-change values into the grid, write CC values back out, and diagnose controller numbers while performing.

Pattern Bank and Transpose Tools

Browse reusable ORCA building blocks, reuse your own ideas, and transpose grid notes up or down by semitones.

Integrated Synth Engine

Use built-in synth channels, polyphonic chords, effects, and commander shortcuts to shape sound without leaving the session.

Expanded Pluck Controls

Shape pluck channels with Attack noise, Dampening, and Resonance controls, including ORCA modulation through base-36 values.

Richer Shader Editor

Edit reactive GLSL visuals beside the sequencer with an upgraded shader workflow built for visual-coding sessions.

Custom Theme Editor

Design and save your own color themes for performance, teaching, low-light work, or a personal studio setup.

Portable Project Format

Save complete .orcalot sessions with grid, shader, theme, and synth state, or import legacy .orca grids.

Workspace Recording

Capture ideas quickly with recording controls available directly in the main creative workspace.

Resizable Panels

Resize the synth and reference panels, switch tabs faster, and keep the layout close to the work in front of you.

Language Support

Use Orcalot with expanded language support and refined desktop save behavior for a cleaner daily flow.

Latest Update

Orcalot 3.0.0 makes MIDI controllers feel native to the ORCA workflow. It adds MIDI input operators, matching CC read/write behavior, controller diagnostics, note transposition, Pattern Bank browsing, polyphonic synth chords, and new pluck controls for Attack noise, Dampening, and Resonance.
