LambdaComing soon

A live console.
On one PC.

Lambda turns a Linux PC into a live mixing console. It takes 128 inputs over the network and runs your VST3 plug-ins on any channel. Mix from the desktop app or a web browser.

In development for Linux on x86_64.

Mock-up of the Lambda mixer: one layer of eight channels, eight insert slots each, faders and meters, with the main and cue buses at the right. Layer B is shown.

128 in, 128 out, over the network.

Connect stage boxes over Tunnel, the Quanta network audio protocol, or use AES67 devices or a local audio interface. Each show runs on one clock, at 48 or 96 kHz. If Lambda cannot play a stream, it tells you why.

Two separate networks, A and B. Each input arrives on both.

Plug-ins on any channel.
A crash stays in its rack.

Each channel has up to eight inserts. Use the 25 built-in effects or your own VST3 plug-ins for Linux or Windows. Plug-ins run in their own processes, outside the audio engine. If one crashes, its rack passes unprocessed audio while Lambda starts a new process. Outputs that do not use that rack do not change.

Rack ready. Linux and Windows plug-ins run in separate processes.

The same console on every screen.

The engine runs on the PC and needs no screen. Mix from the desktop app or a browser on the same network. Pair each screen once with a six-digit code. Every screen shares the show's layers and scenes, and each can show its own layer. MIDI and OSC control the engine directly.

Waiting for code

Less than 2 ms through a plug-in rack.

That is from input to output inside the engine at 96 kHz, through one plug-in rack and one built-in effect. It does not include network, converter or plug-in latency.

1.00 msmeasured inside the engine, through a rack with one Linux plug-in

Measured at 96 kHz with 32-frame blocks: 96 frames for every test impulse.

What works today.

Lambda is in development on Linux. This is what works and what comes next.
