Quick Start

Try It Now

Open the virtual pad on any modern desktop, phone, or tablet. Demo walks through selecting and approving one of three simulated agents. Sandbox lets you display every Visual Protocol 1 state, and Show plays the audiovisual performance.

No account, MIDI hardware, API key, or installation is required. The public pad is a simulation and does not connect to an agent.

Install

Install Pad-Lattice as an isolated command:

pipx install pad-lattice

This installs from PyPI without modifying the system Python. Inside an active virtual environment, use python -m pip install pad-lattice instead.

Confirm the installation:

pad-lattice --version
pad-lattice doctor

The normal package includes physical MIDI support, the local browser bridge, and QR pairing.

Control Real Codex in a Browser

Start the virtual surface:

pad-lattice web

Pad-Lattice prints and opens a tokenized loopback administrator URL. Leave this process running; it is both the agent daemon and local browser bridge. Treat that URL as a credential and do not share it.

Launch an integrated session:

pad-lattice codex --label implementation

On the first Pad-Lattice-launched session, run /hooks to review and trust the scoped commands. Prompt, running, approval, and completion states then update automatically. Ordinary codex sessions do not load these hooks or show their review prompt.

When Codex requests permission, select its Agent Scene and tap the lit Approve or Reject control. A decision applies only to the selected session and current request. After 60 seconds without a surface decision, Codex restores its normal keyboard prompt.

Continue with Control Codex for resuming conversations, running several agents, and understanding what each surface state means.

Phone, Tablet, or Laptop

Expose the virtual surface to the trusted local network:

pad-lattice web --lan

The local admin page shows a one-use QR code and six-digit PIN that expire in five minutes. Scan the QR or open the printed LAN URL and enter the PIN. The paired device can reconnect until the daemon stops.

See Connect a Phone, Tablet, or Laptop for one or more devices, network troubleshooting, and Parallels Desktop. LAN mode is for a network you trust; never expose it through a router or use it on public Wi-Fi.

Physical Launchpad

Discover attached hardware and run the supported-device demo:

pad-lattice ports
pad-lattice devices
pad-lattice demo

Demo and Show can also run without MIDI:

pad-lattice demo --surface web
pad-lattice show --surface web

The tokenized local page opens first. Choose Start Demo or Start Show there to start. Its Sound control is muted by default and belongs only to that browser. Use --surface both to keep a Launchpad and every browser synchronized.

Run normal physical control by itself:

pad-lattice daemon --no-greeting

Mirror the same state and actions in browsers at the same time:

pad-lattice daemon --web --no-greeting

Only the daemon owns MIDI ports. Every surface feeds the same selected-session action router, so a tap and a physical press have identical semantics.
